Which microSD to buy: what is the difference between SD, SDHC, SDXC formats and how to choose the right memory card

03/02/2022 by

[ad_1]

Memory cards have become an elegant solution to expand the internal storage of our gadgets. Today, in any electronics and communications store, you can easily purchase a popular microSD card format for your phone, camera or tablet. But such a purchase is fraught with some pitfalls. The user may simply overpay or unexpectedly run into problems: the memory may work too slowly or, in fact, be smaller. Below we will give some recommendations that will help you choose and buy a microSD card correctly.

♥ BY TOPIC: The best gadgets for Apple, home, work and play from AliExpress (updated daily).

Our detailed video:

1. SD card compatibility

Micro SD card formats

All microSD cards fit physically into slots of their format. However, not all devices work properly. It turns out that there are four varieties of this format with their own standards. They define compatibility. Many people have heard about the three main microSD formats: SD, SDHC, SDXC (or microSD, microSDHC and microSDXC). Full-size cards and their smaller counterparts operate on the same specification. In June 2018, a fourth format, SDUC, was announced. But such cards will become available over time.

Each of these formats belongs to the SD family, but they do not work in the same way. As a result, the formats are not backward compatible. New cards cannot be used with equipment that natively supports only older formats.

What is the difference between microSD, microSDHC, microSDXC and microSDUC formats?

• microSD has a capacity of up to 2 GB and can work in any slot for microSD cards.
• microSDHC has a capacity of 2 GB to 32 GB and will work on hardware that supports SDHC and SDXC.
• microSDXC has a capacity of 32 GB to 2 TB and is only supported in devices that work with SDXC.
• microSDUC supports cards up to 128 TB, but the device also requires support for this format.

It is not enough to check the compatibility of a specific memory card with the equipment; some other details should be taken into account.

Capacity and file system

microSD card capacityIt turns out that even hardware that supports microSDXC cards is unable to automatically work with all cards of this format. So, for example, Samsung Galaxy S9 officially supports memory cards up to 400 GB. No one guarantees that a 512 GB drive will work correctly on a smartphone. When using a memory card to transfer files from a mobile device to a computer, make sure that the PC supports the file system in which the media is formatted. For example, microSDXC cards use the exFAT system by default. Both Windows and macOS have supported this file system for quite some time.

Ultra high speed support

The SDHC and SDXC formats can support the Ultra High Speed ​​(UHS) bus interface, which enables higher data transfer rates. There are three versions of UHS:

• UHS-I with bus speeds up to 104 MB/s.
• UHS II with bus speeds up to 312 MB/s.
• UHS III with bus speeds up to 624 MB/s.

To benefit from high-speed UHS technology, equipment must support it. Memory cards will also work in the old slots, but with a speed reduced to 25 MB / s. The second and third generation UHS also have an additional row of contacts on the map. They will be read on devices that support the first generation, but also at a reduced speed. Roman numerals located next to the card logo will tell you about the generation of the interface.

2. MicroSD card speed

Determining the speed of a microSD card is even more difficult than deciphering the formats and their compatibility. There are at least six ways to show the card’s capabilities, and it’s not uncommon for manufacturers to use them all at once.

microSD card specifications

Speed ​​class

Speed ​​class

This parameter directly shows the minimum write speed to the memory card in megabytes per second. There are four speed classes defined as follows:

• Class 2: at least 2 MB/s.
• Class 4: at least 4 MB/s.
• Class 6: at least 6 MB/s.
• Class 10: at least 10 MB/s.

Displaying the card’s base performance helps you understand if it’s generally suitable for specific tasks. But this parameter does not say anything about the maximum speed of operation. As a result, it is theoretically possible that a class 2 memory card will be faster than its class 6 counterpart. But class 10 cards should always be faster than their smaller counterparts due to the bus speed of 25 MB / s compared to 12.5 MB / s on cards of previous classes.

UHS speed class

UHS speed class

The UHS speed rating indicates the minimum write speed for microSD cards that support UHS-I, II, and III. We highlight this as a separate category, since some manufacturers write two classes at once on their cards. There are two options for the UHS speed class:

• U1: write speed of at least 10 MB / s.
• U3: write speed of at least 30 MB / s.

Application Launch Speed ​​Performance Class

Performance class for microSD card application launch speed

This setting specifies the minimum supported write speed of 10 MB/s, as well as the minimum random read and write speed, measured in input/output operations per second (IOPS). Such a class guarantees the desired level of performance when storing Android applications on a memory card and running programs from it. There are two classes here:

• A1 with minimum random read speeds of 1500 IOPS and random write speeds of 500 IOPS.
• A2 with minimum random read speeds of 4000 IOPS and random write speeds of 2000 IOPS.

This class of performance makes you pay attention when planning to install Android applications on a microSD memory card. But it is not at all necessary that the carrier should be marked A1 or A2. Some cards without this class indicator may work well and even better than marked ones.

Video Speed ​​Class

This indicator is responsible for the minimum sequential recording speed used when shooting video. And the higher its resolution, the greater the speed required. There are five classes of video recording speed:

• V6 with a minimum write speed of 6 MB/s.
• V10 with a minimum write speed of 10 MB/s.
• V30 with a minimum write speed of 30 MB/s.
• V60 with a minimum write speed of 60 MB/s.
• V90 with a minimum write speed of 90 MB/s.

Rated speed

It is logical to assume that a higher speed class equates to higher overall performance, with UHS cards being even faster. And some manufacturers also indicate the maximum speed of their products.

The figures are given in megabytes per second and will allow you to select the fastest cards. But these speeds are obtained from the tests of the manufacturers themselves. Theoretical indicators relating to the ideal case. Actual performance may be noticeably lower. In practice, external factors that affect the speed of reading and writing usually play a role. So, the time for copying files to a computer will be determined by its characteristics, and the USB cable used.

Relative speed

There is another way that manufacturers show the speed of their cards. It has to do with the recording times of CDs. Back then, the unit of speed was 150 kbps. As drives and discs evolved, 2x, 8x, 48x, and even 52x were advertised. This showed how many times the device is faster than the baseline.

Surprisingly, microSD cards have received such a marking. When we see a 100x mark on a product, it indicates a speed of 100 × 150 kbps, or 15 MB / s. But these indicators refer to laboratory, not real conditions.

3. Which microSD card to choose for a smartphone to take photos and videos

When buying a microSD card, the user usually already has in mind future scenarios for using the drive. It is important to choose exactly the solution that will be involved in the future. For the consumer, the volume and speed of the memory card are most often important, while record numbers are not required. You will have to pay a lot for high-capacity UHS-II U3 ​​high-end cards, but you will not always notice the advantages that determine the high price.

If a microSD card is used to store applications on a smartphone, then you should pay attention to the performance class for startup speed. But if you plan to shoot 4K video on your phone, then the memory size and recording speed should become the priority parameters of the media.

Which microSD card to choose for a smartphone, for taking photos and videos

The SD Card Association recommends using UHS U3 cards for shooting 4K video. And for shooting video with FullHD resolution, ordinary cards of 10 or even 6 class will be enough. If the recording speed is too slow, frame drops will occur and the sound will be interrupted.

Photographers often prefer to use several smaller capacity cards together with one large one. This minimizes the risk of losing all data if the media is damaged. And when shooting in RAW format, you need to remember the impressive size of the image – 50 MB or more. In this case, you will need a card with U1 or U3 speeds and with a format of at least SDHC.

It is worth recalling that there is no fundamental difference between a full-size SD card and a microSD card connected via an adapter. If the device only supports a full-size card, then it is quite possible to use an adapter with a microSD card.

4. Fake microSD cards

At first glance, the advice to avoid fakes seems obvious, but buying non-original memory cards is very easy. Often an unknown seller offers a low price for branded memory cards. In this case, we can talk about an increased risk of running into a fake. A few years ago, a SanDisk engineer claimed that about a third of all SanDisk cards were actually non-original products. It is unlikely that this number has decreased since then.

When purchasing memory cards in an unknown store, it is better to read reviews about it first. Counterfeit microSDs usually show the capacity listed on the packaging correctly, but they won’t actually be able to store that amount of data. Free space on the map will run out unexpectedly quickly. You can check the actual capacity of your drive using the H2testw utility for Windows or F3 for Mac and Linux.

5. Buy branded microSD cards

Each of us had flash memory cards that once stopped working for no apparent reason. It is believed that these drives are generally highly reliable, but their death leads to the loss of all data stored there. It is for this reason that the purchase of memory cards manufactured by large brands is always preferable to cheap nameless cards. From a quality product, you should expect better performance, increased levels of reliability, protection from water, shock and even X-rays at airports. Big name manufacturers often provide a lifetime warranty and access to data recovery software. This standard is offered by SanDisk and Lexar.

What is the ideal microSD card?

Thanks to our advice, you can avoid mistakes when purchasing a memory card. It remains only to figure out which card is needed. Does it require a high write speed and should it be over 400 GB? The formed criteria and information about the standards and speeds of microSD cards, indicated above, will allow you to make the right choice.

DISCOUNT ($ 979 → $ 379) SteamWorld Quest: Review of an RPG Card Game for iPhone and iPad

11/11/2021 by

[ad_1]

The product of the Swedish studio Image & Form, called SteamWorld Tower Defense, even though it was released for the Nintendo DSi, was noticed and appreciated by gamers. The company decided not to develop the original genre of the game, but to use the existing successful style. The main thing is that the idea caught on.

This is how a whole drawn world appeared with grotesque and recognizable characters, bright, juicy and cheerful with a bunch of Easter eggs and self-irony. And in the SteamWorld universe, a whole scattering of games with a variety of mechanics has appeared: the platformer SteamWorld Dig, the fantastic turn-based strategy SteamWorld Heist, similar to the action-RPG SteamWorld Dig2. But they are united not only by the style, but also by the heroes.

The game SteamWorld Quest Hand of Gilgamech just begins with the fact that one of the heroes of the game SteamWorld Heist tells the child a fairy tale ….

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Once again, the Swedes decided to experiment with genres. Their new creation is difficult to describe in one word – it is a kind of mixture of card games, RPG and fantasy. The story begins with the fact that two characters – Armilli and Copernicus, go into the forest in search of an important mushroom. The heroes, which is usual for the world with references to steam-punk, are the very steam glands. Only one of the girls is a classic warrior in armor, and the other is a bespectacled wizard in a wide-brimmed hat. The classic combination is a warrior and a magician!

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Our heroes quickly find themselves in the thick of things, where we must manage to destroy the plans of our enemies and look for powerful artifacts. The creators of the game were not afraid to mix genres and jump from one to another – it’s even more interesting this way!

The plot leads us through 19 acts, but besides the main path it will not be difficult to find branches. There, our heroes will be able to find treasures, gain experience and pump themselves in the fight against enemies, smash their heads over riddles or buy from a merchant. Three more characters will join Armilli and Copernicus over time, complementing the team and significantly increasing the variability of combat tactics.

Combat is a key element of the game that cannot be ignored. So if you are not a fan of card RPG battles, then you will have to dive into this world. Before the battle, the player will have to choose those three characters who will defend the honor of the glorious squad. And here the decision must be taken deliberately, because the heroes can act in concert and complement each other. Each character has his own deck of 8 cards – the very same combat skills. The player receives six cards from different heroes in his hands and lays out three cards as his turn. Each of them has its own effect, certain combinations play in their own way, up to combos.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

After the opponent’s move, the number of cards on hand is added to six. Some cards – ordinary spells and blows that give a resource, an analogue of mana – gears. Other, more cunning abilities, just require the use of accumulated magic. Some cards are one-time use, and those that have been cleared can be used again after being shuffled due to a prolonged battle.

Our heroes start with the simplest set, and the friends who join will initially own the pumped cards. And the more complex the weapons become in the deck format, the more varied the strategy will be.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Of course, our main weapon – cards, have to be mined in this fabulous world, since there are many opportunities for this. The cards are in hidden chests, in some locations, or they can appear by simple crafting. In total, each character has 20 elements in the luggage, but as already mentioned, you can take only 8 of them into battle.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Decks will have to constantly shuffle and adapt to opponents who are very different in their fighting techniques and defensive mechanics. There are over a hundred unique cards in the game. And the specialization of our characters in one direction or another (magic, physical damage, dirty tricks) help to more clearly define the skills of the squad. The experience gained during the battles improves the characteristics of the heroes, everything is standard here for an RPG.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

SteamWorld Quest Hand of Gilgamech is not a traditional roguelike, but more of a story-driven story. The company itself appears to be relatively linear, with confusing locations and offshoots trying to fix it somehow. Nevertheless, you will have to immerse yourself in the game for 15-20 hours. But the fun game universe created by the Swedes does not force players to strain at all, but simply gives them pleasure from a juicy picture, a general hand-drawn steampunk style, selected music and rich sound. And all this is abundantly seasoned with sharp humor. Yes, by the end of the game you will understand that there is no point in shuffling cards and fighters – proven bundles will pull out almost any fight.

It turns out that with the increase in the level of the game it becomes even easier. Perhaps the SteamWorld Hand of Gilgamech can be forgiven for this slight imbalance. Still, the advantages of the game outweigh its disadvantages, and Image & Form perfectly complemented its world with another colorful adventure.

Search, no network or why the iPhone does not see the SIM card

18/09/2021 by

[ad_1]

Sometimes users face such a problem while traveling, using roaming, after reinstalling iOS, hardware repair (battery or display replacement) of the smartphone, or a long period of inactivity (without recharging) – the operator logo disappears on the iPhone and there is no connection to the cellular network. Let’s try to figure out what is the cause of the “breakdown” in such cases and how to fix it.

The problem is aggravated by the fact that the employees of service centers in Russia, Ukraine, Belarus, etc. They are far from always able to identify the real reason for the lack of connection to the cellular network (or deliberately hide it) and perform a number of expensive procedures – from a simple reinstallation of iOS and ending with hardware repair using a soldering iron and other “jewelry” tools.

Check if the SIM card is working?

Unfortunately, SIM cards also fail. Therefore, first of all, check if the SIM card in your iPhone works. This can be done, for example, by installing a SIM card in another smartphone.

What to do if instead of the operator on the iPhone it says “no network” or the smartphone does not see the SIM card after repair (flashing)

In the event of the described problem, first of all, you need to look at the set time – if the smartphone does not display the current time and date correctly, then you need to perform the following simple algorithm of actions:

1… Connect the device to an active Wi-Fi network;

No network or why the iPhone does not see the operator's SIM card

2… Go to Settings → The main → date and time;

No network, search, or why the iPhone does not see the operator's SIM card

3… Toggle the checkbox “Automatically»In the active position (if set by default – turn it off and on);

4… Restart your iPhone.

No network, search or what to do when the iPhone does not see the operator’s SIM card while roaming abroad

If you have ever traveled abroad with your iPhone, you may have encountered such a problem. You turned off your smartphone during the flight, and when you turned it on, your device does not connect to the cellular network, but displays the message “No network”. What to do?

The Apple Support Forum has a corresponding discussion thread with a million pages to read. But even if you honestly start reading everything in order to figure it out, you will not get an answer to your question even after a few hours of careful reading.

System message “No network” (Search network) appears when your iPhone or iPad (yes, the problem is also relevant for Apple tablets) cannot connect to it, or connects to an operator, but cannot establish a connection either to the Internet or to the cellular network. You can even see the name of the operator who serves you – but then it will disappear anyway.

This error can have several reasons at once. But first, the most common and simplest of them should be excluded. And anyone can do it.

Switch from LTE (4G) to 3G

1… Open up Settings your iPhone or iPad.

2… Please select Cellular → Data Options…

Cellular Data Settings on iPhone

3… Go to section Voice and data and change LTE to 3G or 2G.

Cellular Data Settings on iPhone

Why should you do this? Experience shows that not all mobile operators abroad provide roaming in 4G / LTE networks. As a result, which is logical, your iPhone or iPad is not connected to the networks – simply because there is nothing there for “foreigners”. And the easiest way to solve this problem is to look for networks of the previous, third generation (3G), because it is difficult to imagine a more or less developed country where there are none.

Let’s repeat – this situation has nothing to do with 4G coverage of foreign operators. They can provide 4G networks to local subscribers, but not to newcomers.

Try it – it really helps :).

Did not help?

Well, let’s look at the solutions that Apple offers us.

1. Turn off and on your iPhone (iPad)

2. Update operator settings

For this:

– Connect to the Internet via Wi-Fi or cellular operator.
– Select Settings → The main → About this device… If your operator has prepared an update to the settings, you will be prompted to update to them.

3. Take out the SIM card and insert it back

4. Reset network settings

Settings → The main → Transfer and reset iPhone → Reset → Reset network settings… Keep in mind that this operation resets Wi-Fi passwords, cellular network settings, and preset VPN / APN settings.

6. Contact your cellular operator for help

Check with him if the account is active, if there are any technical problems with communication in your area.

7. Reset iPhone or iPad to factory settings (detail)

What to do if the Internet does not work on iPhone while roaming

1. Go to Settings → cellular and see if the slider opposite the inscription is turned on Cellular data…
2… If you are abroad, check if the data roaming settings are active (Settings → cellular → Data parameters → data roaming).

How can your SIM card be hacked and how can you protect yourself?

19/07/2021 by ALOK DAS

[ad_1]

The regular SIM card that is installed in our phones can actually pose a serious security risk. It turns out that this piece of plastic with a microcircuit is susceptible to hacking, but it is in the user’s power to protect himself, his data and his smartphone.

♥ BY THEME: Why am I connected to Wi-Fi but no internet?

And with new online threats popping up every day, we need to be aware of more security holes. For example, you probably already know that your smartphone’s operating system needs regular updates. This is the only way to prevent threats. It should be understood that a SIM card can also be a source of vulnerability in the built-in security system. In this article, we will tell you how attackers can use your SIM card to access various services and data, as well as give advice on security measures in this area.

Simjacker

In September 2019, security researchers at AdaptiveMobile Security announced that they had discovered a new vulnerability. She was named Simjacker. This sophisticated attack targets SIM cards. A piece of spyware-like code is sent to the target device via SMS.

If the user opens such a message, the code will be activated and hackers will be able to spy on calls and messages from this phone, as well as track its location.

How are SIM cards hacked and how can you avoid it?

The vulnerability works through software called S @ T Browser, which is part of the SIM Toolkit (STK). Many telephone operators use it on their SIM cards. SIMalliance Toolbox Browser is a way to access the Internet. Basically, it is a basic web browser that allows service providers to interact with web applications such as email.

However, today most people use browsers such as Chrome or Firefox on their devices, the S @ T browser is rarely in demand. However, specialized software is still installed on a large number of devices, making them vulnerable to the Simjacker attack.

Researchers believe that this attack was used in many countries. It is stated that the S @ T protocol “is used by mobile operators in at least 30 countries with a combined population of more than a billion people.” These are mainly the Middle East, Asia, North Africa and Eastern Europe.

The experts concluded that the exploit was developed and used by a specific private company. She worked with the authorities of different countries to monitor certain demographic groups such as journalists and activists.

All types of phones are affected, including iPhones and Android devices. Simjacker even works with embedded SIM (eSIM) cards.

♥ BY THEME: SOS: what does it mean?

SIM card re-issue

Call to the call center

Another SIM security issue that you may have heard of is SIM re-issue. For example, hackers used a variation of this technique to hijack the personal Twitter account of the same company’s CEO Jack Dorsey in August 2019. Thanks to this event, many became aware of the potential destructive power of such attacks. And this method uses gimmicks and human engineering, not technical vulnerabilities.

To reissue the SIM, the hacker will first call your carrier. Attackers will pretend to be you and ask you to replace the SIM card. For example, hackers will say they want to migrate to a new device and therefore need a new SIM card. If successful, the phone operator will send them a SIM card.

This way, attackers can steal your phone number and associate it with their device. And all this without removing the SIM card from your device!

As a result of the action, two effects will appear. First, your original SIM card will be deactivated and stop working. And secondly, the hacker will now have control over phone calls, messages and two-factor authentication requests sent to your phone number. This means that third parties will now have enough information to access your accounts, which will block your access to various services.

It is difficult to defend against SIM card reissue because this attack is related to social engineering. The hacker will have to convince the support employee of who the caller is. Once they get your SIM card, attackers will be able to control your phone number. Unfortunately, you may not even know you are being targeted until it’s too late.

Cloning a SIM card

Often times people try to combine SIM card reissue and SIM cloning in the same case. However, cloning a SIM card is more practical than the other option.

In a SIM cloning attack, the hacker first gains physical access to your SIM and then creates a copy of the original.

Cloning a SIM card

Naturally, in order to copy your SIM card, attackers will first physically remove your SIM card from the smartphone. Then the dedicated smart card copying software comes into play, it will copy the unique identification number assigned to your SIM card and transfer it to a blank SIM card.

Cloning a SIM card

After that, a new cloned SIM card will be inserted into the attacker’s smartphone. Once this process is complete, consider that your unique SIM card identification information has all but disappeared.

Now a hacker will be able to track all messages sent to your phone – just like when a SIM is reissued. This means that outsiders will gain access to your two-factor authentication codes, allowing them to hack your social media accounts, email addresses, card and bank accounts, and more.

Hackers can also use your stolen SIM card for fraudulent purposes when they need to provide a unique phone number somewhere.

How to keep your SIM card safe?

If you want to protect your SIM card from such attacks, fortunately, there are some precautions you can take.

Protection against attacks provoked by social networks

To protect against SIM swapping, make it difficult for hackers to find information about you. Attackers will try to use data they find about you on the Internet, such as the names of friends and family members or your address. This information will help you convince the customer service representative of who the caller is.

Try to block this information by setting access only for friends in your Vkontakte or Facebook profile and restricting the publicly available information that you share on other sites. Also, remember to delete old accounts that you no longer use so that they don’t become a target of a hack.

Another way to protect yourself from SIM reissue is to watch out for phishing. Hackers may try to trick you into obtaining additional information in order to use it to copy your SIM card. Watch out for suspicious emails or login pages. Be careful when entering login information for any account you use.

Finally, think about which two-factor authentication methods you are using. Some two-factor authentication services send an SMS message with a special code to your device. This means that if your SIM is compromised, hackers will gain access to your accounts, even if you have two-factor authentication enabled.

Instead, use another authentication method, such as the Google Authentication app. This way, authentication becomes tied to your device and not to your phone number, making it more secure against SIM re-issue attacks.

Set up SIM card lock

To protect against SIM attacks, you should also ensure that some protection measures are activated on your SIM card. The most important and simplest security measure you can implement is adding a PIN. Thus, if someone wants to make changes to your SIM card, they will need to enter a secret PIN.

But before setting up such a SIM card lock, make sure you know the PIN code provided to you by your network operator. To set it up, on your Android device, go something like this: Settings → Lock screen and security → Other security settings → Set up SIM card lock or Settings → Passwords and security → <Оператор> → Blocking SIM-cards… Here you can activate the SIM card lock slider.

On iPhone, go to Settings → cellular → SIM PIN… Then enter your existing PIN for confirmation, press Done and the SIM card lock will be activated.

Other safety tips

As always, you should use strong and individually generated passwords. Do not reuse old passwords or use the same password for multiple accounts.

Also, make sure that your answers to password recovery questions are not publicly available, for example, it is not your mother’s maiden name, which is a classic.

Protect your device from SIM attacks

Mobile attacks are becoming more sophisticated. But there are available remedies against these types of attacks, such as keeping your personal information private and setting up a SIM card lock.

However, in general, phones are becoming more secure than before, and you can always check if your phone has been jailbroken. And the security features at your disposal help you protect yourself from malicious acts by third parties.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

09/02/2021 by ALOK DAS

[ad_1]

The product of the Swedish studio Image & Form, called SteamWorld Tower Defense, was released for the Nintendo DSi, but it was noticed and appreciated by gamers. The company decided not to develop the original genre of the game, but to use the existing successful style. The main thing is that the idea caught on.

Download a game SteamWorld Hand of Gilgamech for iPhone and iPad (App Store)

This is how a whole drawn world with grotesque and recognizable characters appeared, bright, juicy and cheerful with a bunch of Easter eggs and self-irony. And in the SteamWorld universe, a whole scattering of games diverse in mechanics has appeared: the platformer SteamWorld Dig, the fantastic turn-based strategy SteamWorld Heist, similar to the action-RPG SteamWorld Dig2. But they are united not only by style, but also by heroes.

The game SteamWorld Hand of Gilgamech just begins with the fact that one of the heroes of the game SteamWorld Heist tells the child a fairy tale ….

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Once again, the Swedes decided to experiment with genres. Their new creation is difficult to describe in one word – it is a kind of mixture of card games, RPG and fantasy. The story begins with the fact that two characters, Armilli and Copernicus, go into the forest in search of an important mushroom. The heroes, which is usual for the world with references to steam-punk, are the very steam glands. Only one of the girls is a classic warrior in armor, and the other is a bespectacled wizard in a wide-brimmed hat. The classic combination is a warrior and a magician!

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Our heroes quickly find themselves in the thick of things, where we must manage to destroy the plans of our enemies and look for powerful artifacts. The creators of the game were not afraid to mix genres and jump from one to another – it’s even more interesting this way!

The plot leads us through 19 acts, but besides the main path, it will not be difficult to find branches. There our heroes will be able to find treasures, gain experience and pump themselves in the fight against enemies, puzzle over riddles or buy from a merchant. Three more characters will join Armilli and Copernicus over time, complementing the team and significantly increasing the variability of combat tactics.

♥ BY TOPIC: 100 best games for iPhone and iPad according to Yablyk edition.

Combat is a key element of the game that cannot be ignored. So if you are not a fan of card RPG battles, then you have to dive into this world. Before the battle, the player will have to choose those three characters who will defend the honor of the glorious squad. And here the decision must be taken deliberately, because the characters can act in concert and complement each other. Each character has his own deck of 8 cards – the very same combat skills. The player receives six cards from different heroes in his hands and lays out three cards as his turn. Each of them has its own effect, certain combinations play in their own way, up to combos.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

After the opponent’s move, the number of cards on hand is added to six. Some cards are ordinary spells and blows that give a resource, an analogue of mana – gears. Other, more cunning abilities, just require the use of accumulated magic. Some cards are one-time use, and those that have been cleared can be used again after being shuffled due to a prolonged battle.

Our heroes start with the simplest set, and the friends who join will initially own the pumped cards. And the more complex weapons become in deck format, the more varied the strategy will be.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Of course, our main weapon – cards, have to be mined in this fabulous world, since there are many opportunities for this. The cards are in hidden chests, in some locations, or they can appear through simple crafting. In total, each character has 20 elements in the luggage, but as already mentioned, you can take only 8 of them into battle.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

Decks will have to constantly shuffle and adapt to opponents, who are very different in their fighting techniques and defensive mechanics. There are over a hundred unique cards in the game. And the specialization of our characters in one direction or another (magic, physical damage, dirty tricks) help to more clearly define the skills of the squad. The experience gained during battles improves the characteristics of the heroes, everything is standard here for an RPG.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

The SteamWorld Hand of Gilgamech is not a traditional roguelike, but more of a storyline. The company itself appears to be relatively linear, with confusing locations and offshoots trying to fix it somehow. Nevertheless, you will have to dive into the game for 15-20 hours. But the fun game universe created by the Swedes does not make players tense at all, but simply gives them pleasure from a juicy picture, a general hand-drawn steampunk style, selected music and rich sound. And all this is abundantly seasoned with sharp humor. Yes, by the end of the game you will understand that there is no point in shuffling cards and fighters – proven bundles will pull out almost any fight.

SteamWorld Hand of Gilgamech: Review of an RPG Card Game for iPhone and iPad

It turns out that as the level of the game increases, it becomes even easier. Perhaps the SteamWorld Hand of Gilgamech can be forgiven for this slight imbalance. Nevertheless, the advantages of the game outweigh its disadvantages, and Image & Form perfectly complemented its world with another colorful adventure.

In the meantime, there is no need to know about it. ”

Which microSD to buy: what is the difference between SD, SDHC, SDXC formats and how to choose the right memory card

05/01/2021 by ALOK DAS

[ad_1]

Memory cards have become an elegant solution to expand the internal storage of our gadgets. Today, in any electronics and communications store, you can easily purchase a popular microSD card for your phone, camera or tablet. But such a purchase is fraught with some pitfalls. The user may simply overpay or unexpectedly run into problems: the memory may work too slowly or, in fact, be smaller. Below we will tell you about some recommendations that will help you choose and buy a microSD card correctly.

♥ BY TOPIC: The best gadgets for Apple, home, work and leisure with AliExpress (updated daily).

Our detailed video:

In the meantime, there is no need to worry about it. ”

1. SD card compatibility

Micro SD card formats

All microSD cards physically fit into their format slots. However, not all devices work properly at the same time. It turns out that there are four varieties of this format with their own standards. They determine compatibility. Many have heard of the three main microSD formats: SD, SDHC, SDXC (or microSD, microSDHC and microSDXC). Fullsize maps and their scaled-down counterparts work on the same specification. In June 2018, a fourth format, SDUC, was announced. But such cards will become available over time.

Each of these formats belongs to the SD family, but they don’t work the same way. As a result, the formats are not backward compatible. New cards cannot be used with equipment that initially only supported old formats.

What is the difference between microSD, microSDHC, microSDXC and microSDUC formats?

• microSD has a capacity of up to 2GB and can work in any microSD card slot.
• microSDHC has capacities ranging from 2GB to 32GB and will run on hardware that supports SDHC and SDXC.
• microSDXC has capacities ranging from 32GB to 2TB and is only supported on devices running SDXC.
• microSDUC supports cards up to 128 TB, but the device is also required to support this format.

It is not enough to check the compatibility of a particular memory card with the equipment; some other details should also be taken into account.

Capacity and file system

MicroSD card capacityIt turns out that even hardware that supports microSDXC cards is not able to automatically work with all cards of this format. So, for example, Samsung Galaxy S9 officially supports memory cards up to 400 GB. No one guarantees that a 512 GB drive will work correctly on a smartphone. When using a memory card to transfer files from a mobile device to a computer, make sure the PC supports the file system in which the media is formatted. For example, microSDXC cards use the exFAT system by default. Both Windows and macOS have been supporting this file system for quite some time.

Ultra High Speed ​​Support

SDHC and SDXC formats can support the Ultra High Speed ​​(UHS) bus interface, which allows for faster data transfer rates. There are three versions of UHS:

• UHS-I with a bus speed of up to 104 Mbit / s.
• UHS-II with a bus speed of up to 312 Mbit / s.
• UHS-III with a bus speed of up to 624 Mbit / s.

To benefit from the use of high-speed UHS technology, equipment must support it. Memory cards will work in old slots, but at a speed cut down to 25 Mbps. The second and third generation UHS also have an additional row of contacts on the card. They will be read on devices that support the first generation, but also at a reduced speed. And the generation of the interface will be told by the Roman numerals located next to the card logo.

2. Speed ​​of microSD card

Determining the speed of a microSD card is even more difficult than decrypting formats and their compatibility. There are at least six ways to show the capabilities of a card, and manufacturers often use all of them at once.

MicroSD card specifications

Speed ​​class

Speed ​​class

This parameter directly shows the minimum write speed to the memory card in megabytes per second. There are four speed classes, defined as follows:

• Class 2: not less than 2 Mbit / s.
• Class 4: not less than 4 Mbit / s.
• Class 6: not less than 6 Mbps.
• Class 10: not less than 10 Mbps.

Displaying the baseline performance of a map helps you understand if it is generally appropriate for a specific task. That’s just about the maximum speed of work, this parameter says nothing. As a result, it is theoretically possible that a Class 2 memory card will be faster than its Class 6 counterpart. But cards of the 10th class should always be faster than their younger counterparts due to the bus speed of 25 Mbit / s compared to 12.5 Mbit / s on the cards of the previous classes.

UHS Speed ​​Class

UHS Speed ​​Class

UHS Speed ​​Indicates the minimum write speed for microSD cards that support UHS-I, II, and III. We distinguish this as a separate category, since some manufacturers write two classes at once on their cards. There are two options for UHS Speed ​​Class:

• U1: write speed is not less than 10 Mbps.
• U3: write speed not less than 30 Mbps.

Performance class by application launch speed

Performance class for the speed of launching applications of microSD cards

This parameter defines the minimum supported write speed of 10 Mbps and the minimum random read and write speed, measured in input / output operations per second (IOPS). This class guarantees the desired level of performance when storing Android applications on a memory card and running programs from it. Two classes are distinguished here:

• A1 with minimum 1500 IOPS random read and 500 IOPS random write.
• A2 with minimum 4000 IOPS random read and 2000 IOPS random write.

This class of performance makes you stand out when planning the installation of Android applications on a microSD card. But it doesn’t have to be A1 or A2 on the media. Some maps without a pointer of this class can work well and even better than marked ones.

Video speed class

In the meantime, there is no need to worry about it. ”

This indicator is responsible for the minimum sequential write speed used when shooting video. And the higher its resolution, the more speed will be required. There are five classes of video recording speed:

• V6 with a minimum write speed of 6 Mbps.
• V10 with a minimum recording speed of 10 Mbps.
• V30 with a minimum recording speed of 30 Mbps.
• V60 with a minimum recording speed of 60 Mbps.
• V90 with a minimum write speed of 90 Mbps.

Rated speed

It makes sense to assume that a higher speed class corresponds to a higher overall performance, while UHS cards turn out to be even faster. And some manufacturers also indicate the maximum speed of their products.

The figures are given in megabytes per second and will allow you to select the fastest cards. But these speeds are obtained from the tests of the manufacturers themselves. Indicators are theoretical, referring to an ideal case. Real performance may be noticeably lower. In practice, external factors that affect read and write speed usually play a role. So, the time for copying files to a computer will be determined by its characteristics, and the USB cable used.

Relative speed

There is another way that manufacturers show the speed of their cards. It has to do with the timing of CDs. Then the unit of measurement of speed was 150 kbit / s. As drives and discs evolved, advertisements included the designations 2x, 8x, 48x, and even 52x. Thus, it was shown how many times the device is faster than the baseline indicator.

Surprisingly, microSD cards also received this mark. When we see a 100x mark on a product, this indicates a speed of 100 × 150 kbps or 15 Mbps. But even these indicators refer to laboratory, not real conditions.

3. Which microSD card to choose for a smartphone, for taking photos and videos

When buying a microSD card, the user usually has future scenarios for using the drive in mind. It is important to choose exactly the solution that will be used in the future. For the consumer, the volume and speed of the memory card are most often important, while record indicators are not required. Top-end high-capacity UHS-II U3 ​​cards will cost you a lot, but you won’t always see the benefits that drive the high price.

If a microSD card is used to store applications on a smartphone, then it is worth paying attention to the performance class in terms of launch speed. But if you plan to shoot 4K video on your phone, then the priority parameters of the media should be memory capacity and recording speed.

Which microSD card to choose for a smartphone for taking photos and videos

The SD Card Association recommends using UHS U3 cards for 4K video recording. And for shooting videos with FullHD resolution, ordinary cards of 10 or even 6 class are quite enough. If the recording speed is too slow, frame drops will occur and audio will be interrupted.

Photographers often prefer to use several smaller cards together on one large card. This minimizes the risk of losing all data in the event of media damage. And when shooting in RAW format, remember the impressive size of the picture – 50 MB or more. In this case, you need a card with U1 or U3 speeds and at least SDHC format.

It is worth recalling that there is no fundamental difference between a full-sized SD card and a microSD card connected via an adapter. If the device only supports a full-size card, then it is quite possible to use an adapter with a microSD card.

4. Counterfeit microSD cards

At first glance, the advice to avoid counterfeiting sounds obvious, but buying non-original memory cards is very easy. An often unknown seller offers a low price for branded memory cards. In this case, we can talk about an increased risk of running into a fake. A few years ago, a SanDisk engineer stated that about a third of all SanDisk cards are actually non-original products. This number has hardly decreased since then.

When purchasing memory cards from an unknown store, it is better to read reviews about it first. Counterfeit microSDs usually correctly show the capacity indicated on the packaging, but in fact they cannot store that amount of data. Free space on the map will run out unexpectedly quickly. You can check the actual drive capacity using the H2testw utility for Windows or F3 for Mac and Linux.

5. Buy microSD from well-known brands

Each of us had flash memory cards that once stopped working for no apparent reason. These drives are generally believed to have high reliability, but their destruction results in the loss of all data stored there. It is for this reason that the purchase of memory cards made by large brands is always preferable to cheap unnamed cards. From a quality product, expect better performance, increased reliability, water resistance, shock resistance and even X-ray protection at airports. Renowned manufacturers often provide a lifetime warranty and access to data recovery software. Such a standard is offered by SanDisk and Lexar.

Do I have to stick the number on the back of the bank card, if sometimes I have to hand it over to the seller?

Bank cards have become an integral attribute of the life of a modern person. But along with the convenience of refusing cash, risks also arise. Fraudsters take advantage of the credulity or carelessness of citizens and steal their money. And a bank card becomes the key to deferred savings.

You can often find a simple and effective means of protection – a sealed or smeared code on the back of a credit card. Does this make sense, and does such a solution work?

So that a three-digit number (security code) on the card does not see an outsider offering, for example, stick this place. This number itself is called the CVV-2 code or CVC2 from Card Verification Value / Code. The name may vary depending on the payment system. But the essence of this code does not change – with its help, an online payment is confirmed. In fact, knowing the data of the card: its number, validity date and this same code, anyone can make a payment from it.

Initially, the code was located on the inside of the card so that it could not be seen by an outsider. But this measure of protection is, of course, naive. It will not be difficult for an attacker to spy a number and remember it. One has only to pay by card in a restaurant or in a store, passing for payment to strangers, as risks arise. Nothing prevents a person unfamiliar to you to quietly take a photo of a card, use a hidden video camera or rewrite its data, and then try to pay online using them. And this is quite feasible, because not all operations require confirmation in the form of a code transmitted via SMS or mobile application. You can find many services that do not need additional verification. This is exactly what fraudsters need. They can order their own food, book a hotel, purchase digital goods …

Payments through questionable online stores or clone sites of popular services are also dangerous. In fact, you are transferring your card details to strangers. No one guarantees that this information will not leak or will not be used for payments for other purposes. And the cardholder will suddenly discover that a certain amount has disappeared from her. For payments on the Internet, it is better to create a separate card, but do not keep money on it, replenishing only the amount necessary for payment. You can set a spending limit for such a card. And for the main card it’s better to prohibit making payments via the Internet.

Such risks force cardholders to close the code on the back. Perhaps this will not bring benefits, but there will certainly not be harm from this. But to cover up the numbers with a marker or even erase them is definitely not worth it. If you close the CVV code, then so as not to harm the card. An opaque adhesive tape, corrector or washable marker are perfect for these purposes. In this case, the code is worth remembering, as you yourself may need it when making a payment on the Internet.

And in order to accurately minimize the risks of card circulation, it is best to switch to contactless payments. Services such as Apple Pay, Samsung Pay, Google Pay or the domestic World of Pay are already supported almost everywhere where there are terminals for receiving payments. It is not necessary to physically take out and use the card, so no one will be able to spy on its data.

Another protection option involves the use of the PayPal payment system. If the seller works with her, then you do not need to enter data from the card when making a payment. It is enough to log in to PayPal and pay with a card tied to the service. In Russia, this service is not as popular as in Europe and the USA, where at the famous auction eBay is generally the main one. But other payment systems: Yandex and QIWI do an excellent job of this task.
