What is a memory card class and how to choose it? What are MicroSD (SD) cards Classes of SD memory cards

The best memory cards for phones, tablets, cameras, quadcopters and others.

It wasn't that long ago that we had a choice when it came to external memory for your phones, cameras, and portable gaming systems. You could buy the Sony Memory Stick Duo, which seemed like an overkill no matter what your needs, but on the other hand, you could treat yourself to one of the best SD and MicroSD cards for much less.

Considering that most people don't care about the speed and capacity boost Memory Stick Duo offers over SD cards, memory cards have won like Blu-Ray beat HD DVD, resulting in us being saved from the complex memory card variety , left with MicroSD and SD cards.

With the best SD cards on the market currently coming from a variety of tech companies being used in everything from DSLR cameras to Nintendo Switch consoles, we felt it necessary to curate our own ranking, leading you to what will inevitably be your tiniest property. Below you will find a ranking of the best MicroSD memory cards, followed by a buyer's guide in which we will explain all the features of MicroSD and understand their speeds and characteristics.

The best memory cardsMicroSD andSD in 2018:

Samsung Evo Plus

The best and most versatile card MicroSD.

Capacity Interface: MicroSD.

  • pros: Fast | Reliable;
  • Minuses: Darling | Not the fastest;

The best SD card you can buy is technically a MicroSD memory card, although it can be used at full size with the appropriate adapter. While it's not the most resilient MicroSD card on the market, the Samsung Evo Plus's 100 megabytes per second (MB/s) write speed and 90 MB/s write speed are impressive. Not only this, but the wide range of sizes available to choose from, be it 32GB or 128GB, makes the Evo a good choice.

Samsung Pro+ (Plus)

Best card MicroSD for video.

Capacity: 32 GB, 64 GB, 128 GB | Interface: MicroSD.

  • pros: Reliability | High speeds;
  • Minuses: Expensive;

If you shoot a lot, especially in 4K, then you'll need a reliable MicroSD card that can quickly record large amounts of data, which is what the Samsung Pro+ does. This is a U3 rated MicroSD memory card with read/write speeds of 95 MB/s and 90 MB/s. The fast speeds available from the Samsung Pro+ memory card would be largely overkill for everyday tasks in a smartphone, but for 4K video recording it's a fantastic memory card.

SanDisk Extreme Plus

Flagship map memory MicroSD.

Capacity: 32 GB, 64 GB, 128 GB | Interface MicroSD.

  • pros: Very high speeds | Recording small files;
  • Minuses: Expensive;

SanDisk claims that this MicroSD card can read up to 95 MB/s and write up to 90 MB/s, and the card comes quite close to those speeds in tests. This makes the memory card extremely fast, and with smaller files the speed increases even faster, meaning it's a great card for action cameras, quadcopters or pocket cameras. Again, this is a bit of a pricey card, but if you don't mind spending a little more, you'll get a great MicroSD card for your needs.

Lexar 1000x

A memory card with excellent value for money.

Capacity: 32 GB, 64 GB, 128 GB | Interface: MicroSD.

  • pros: Good price | Included USB 3.0 adapter;
  • Minuses: Not the fastest card | Inconsistency;

The Lexar 1000x isn't the fastest microSD card on the market, but that doesn't stop it from being one of the best because of its other benefits. For example, the reading speed of a memory card remains the fastest, and moreover, the memory card is cheaper than most of its competitors. While it can't offer the same write speeds, the difference won't be noticeable to most people. The memory card also comes with a MicroSD to USB 3.0 adapter, making it easy to transfer your files to your PC.

SamsungEvoSelect

Another great universal card MicroSD.

Capacity: 32 GB, 64 GB, 128 GB, 256 GB | Interface: MicroSD.

  • pros: High speeds | Decent price;
  • Minuses: Amazon Exclusive;

As you can probably guess from the number of entries in our ranking of the best MicroSD memory cards, Samsung makes excellent memory cards that are fast, efficient, and reliable MicroSD cards. The Samsung Evo Select is another great all-rounder that's at home in a digital camera, drone, phone, or Nintendo Switch. While the memory card doesn't necessarily excel at any particular task, the card is powerful enough and performs well. Currently, Samsaung Evo Select MicroSD cards are only available from Amazon. While this makes purchasing a discount card a little more difficult, at least you can buy with confidence from a reputable seller.

Kingston Industrial Class 10 U1

Reliable card MicroSD.

Capacity: 8 GB, 16 GB, 32 GB | Interface: MicroSD.

  • pros: Strong | Withstands high and low temperatures.
  • Minuses: Not amazing performance.

If you're looking for a good MicroSD card that can survive harsh environments like in an action camera, on a quadcopter, or mounted outside in a security camera, then the Kingston Industrial Class 10 U1 is a great choice. First, the memory card can withstand temperatures from -40 to 85 degrees Celsius, the card is shockproof and can withstand x-rays. It's been tested for industrial use and comes with a five-year warranty, so you can use this MicroSD card with confidence.

Kingston microSD Action Camera

The ideal memory card for professionals.

Capacity: 16 GB, 32 GB, 64 GB | Interface: MicroSD.

  • pros: Very durable | Good speed;
  • Minuses: Not surprising if not in an action camera;

If you're looking for a MicroSD card to fit into an action camera like a Go Pro, you'll need something that can record data quickly and also withstand drops, shocks, and water. The excellent Kingston microSD Action Camera memory card comes to your aid - designed specifically for action cameras. This means you get an incredibly durable design as well as fast read and write speeds. This is a bit of an overkill camera for smartphone use, so we recommend using one of the other MicroSD cards in our rating for this purpose, it will better suit your needs.

How to choose a memory cardMicroSD: Tips

You shouldn't look for SD and MicroSD memory cards with a capacity of less than 4 GB simply because the price you'll pay for two and four times that capacity remains virtually the same.

Make sure you factor in shipping costs when ordering a MicroSD card online; you may pay more for postage than for the memory card, especially for low-cost models.

If you're looking for a high-capacity memory card (32GB or larger), make sure your device is SDXC compatible.

If you plan to move files to and from portable devices (tablets or smartphones), consider a microUSB memory card reader such as Leef Access.

Avoid buying memory cards from suppliers with few reviews, as these cards can easily be counterfeit. All stores listed in our rating undergo multi-level verification and are reliable.

SD cards with capacities of 128GB and above tend to be cheaper, as users typically opt for 64GB as this number is often the maximum supported capacity of most mobile devices. Typically, MicroSD cards with an adapter are less expensive than equivalent SD cards.

Please note that all numbers will likely be significantly smaller than formatted.

SD memory cards are usually divided into classes that give a rough idea of ​​the minimum performance. A Class 4 card is guaranteed to offer at least 4 Mbps, while a Class 10 should exceed 10 Mbps.

Likewise, many manufacturers report available speeds in the form of an "x", which is a multiple of 150 Kbps (the read speed of a standard CDROM). The 100x memory card is expected to deliver over 14 Mbps.

If you're planning on buying MicroSD cards just for data storage, don't do it. Flash drives, being cheaper and more reliable, are a better choice.

Best cardsMicroSD Buyer's Guide

First of all, it is important to understand the MicroSD standards, as well as all the markings. There are different types of MicroSD cards, even if they look the same.

Capacity

Let's look at MicroSDHC first. HC stands for High Capacity and covers sizes from 4GB to 32GB. Over 32GB of MicroSDXC memory cards, where XC stands for eXtended Capacity, and the largest cards in this category available for purchase are 200GB. However, the latest phones and tablets, including the HTC 10, claim support for MicroSD cards up to 2TB. Check your device's support before purchasing a card: many devices do not support SDXC and are therefore limited to cards up to 32GB of memory.

Speed

There are three different speed standards, and you may see more than one on the card. The original speed marking is marked inside the letter C (center of the image above). The number indicates the minimum stable write speed, so a “Class 6” card is capable of recording information at a speed of 6 MB/s - that is, 6 megabytes per second. This is a sequential write speed that is only used when writing large amounts of data (such as video recording) to sequential memory locations. This does not apply to 4KB random writes, a typical solution for phones and tablets where small amounts of data are written to random locations.

Most devices capable of recording HD video require Class 10 MicroSD cards, but most Class 10 MicroSD cards are capable of more than the minimum recording speed of 10 MB/s.

This is where UHS comes into play. This stands for Ultra High Speed, and the class is denoted by the letter U. A Class 1 UHS MicroSD card writes at a minimum of 10 MB/s, while a UHS 3 card writes at a minimum of 30 MB/s. With.

You may also see UHS-I or UHS-II on the map. This indicates what technology the Micro SD memory card uses. The UHS-I "Bus" can operate at speeds of up to 104 Mb/s, while the UHS-II bus can transfer data at up to 312 Mb/s. This doesn't mean the card will read and write at these speeds, these are peak performance.

In order to benefit from the faster speeds available from UHS-I or MicroSD UHS-II, you need a device that is compatible with this standard.

You can easily identify a UHS-II card because it has a second row of pins below the main set. All cards tested in this article are Class 10 or UHS-I.

SanDisk showed off at MWC 2016 in Shanghai what the manufacturer calls the world's fastest microSD card for 256 GB - SanDisk Extreme microSDXC UHS-I 256GB.

The new card uses a new speed classification system called Video Class. You'll see this system on cards soon, marked V. Like the original class system, this means the minimum sequential write speed in MB/s and ranges from V6 to V90.

Best cardsMicroSD 2018: Temperature, X-ray and durability

MicroSD memory cards are small and easy to lose, but in addition to purchasing a special case for your card collection, it's important to choose memory cards that can withstand travel and anything else that might compromise their function.

Some manufacturers claim that their cards are waterproof and also X-ray protected. However, these specifications apply to almost all MicroSD cards. The data isn't stored magnetically, so an airport scanner shouldn't pose a problem, as long as you're not trying to read or write data to a non-waterproof card reader underwater, the MicroSD card should be able to survive surface moisture.

The cards can also carry ratings for suitability at certain temperatures, say -25 to +85 degrees Celsius, withstand shock and shock, and more. As long as you're willing to pay more for one of these cards, you may be entitled to a warranty if it suddenly fails because it's been exposed to heat or "shocked."

The warranty, therefore, is the most important among all these things: check not only the duration but also the conditions that the warranty covers.

The best memory cardsMicroSD: Which card should I buy?

Our main recommendation is to stick with reputable manufacturers who can provide a warranty on their cards. Reputable manufacturers include: Toshiba, Samsung, SanDisk, Lexar, Kingston, and Verbatim, among others.

There are many counterfeits and low-quality MicroSDs out there, so make sure you buy from a reputable supplier. If you see a card on Avito that is significantly cheaper than you expected, don’t rush!

Before purchasing a MicroSD card, check the maximum capacity of the device. Some mobile devices are limited to 32GB of memory because they are SDHC and not SDXC. It's tempting to get a 128GB card, but it simply won't work if the device can't access it.

Quadcopters / Action Cameras

If you're buying a MicroSD card with the intention of recording 4K video, look for a UHS-I Class 3 card. Many also recommend the same cards for recording Full HD (1080p) video, especially at high frame rates.

Phones/Tablets

It's difficult to guide a buyer here using general specifications because these devices rely on small file transfer speeds, which is an important difference. We'll take a closer look at mobile card compatibility in the reviews below.

For most people, microSD is just a form factor, but in reality it is not. You can easily insert any microSD card into a standard slot, but not all of them will work, since the cards differ in many ways.

Format

There are three different SD formats, available in two form factors (SD and microSD):

  • SD (microSD) - drives up to 2 GB, work with any equipment;
  • SDHC (microSDHC) - drives from 2 to 32 GB, work on devices supporting SDHC and SDXC;
  • SDXC (microSDXC) - drives from 32 GB to 2 TB (currently maximum 512 GB), work only on devices with SDXC support.

As you can see, they are not backward compatible. Memory cards of the new format will not work on old equipment.

Volume

Support for microSDXC declared by the manufacturer does not mean support for cards of this format with any capacity and depends on the specific device. For example, the HTC One M9 works with microSDXC, but officially only supports cards up to 128 GB inclusive.

Another important point is related to the storage capacity. All microSDXC cards use the exFAT file system by default. Windows has supported it for more than 10 years, it appeared in OS X starting with version 10.6.5 (Snow Leopard), Linux distributions support exFAT, but it does not work out of the box everywhere.

High speed UHS interface


An I or II is added to the UHS card logo depending on the version

SDHC and SDXC cards can support the Ultra High Speed ​​interface, which, with hardware support on the device, provides higher speeds (UHS-I up to 104 MB/s and UHS-II up to 312 MB/s). UHS is backward compatible with earlier interfaces and can work with devices that do not support it, but at standard speeds (up to 25 MB/s).

2. Speed


Luca Lorenzelli/shutterstock.com

Classifying the write and read speeds of microSD cards is as complex as their formats and compatibility. The specifications allow you to describe the speed of cards in four ways, and since manufacturers use them all, there is a lot of confusion.

Speed ​​class


The speed class macro for regular cards is a number inscribed in the Latin letter C

The Speed ​​Class is associated with the minimum write speed to a memory card in megabytes per second. There are four in total:

  • Class 2- from 2 MB/s;
  • Class 4- from 4 MB/s;
  • Class 6- from 6 MB/s;
  • Class 10- from 10 MB/s.

By analogy with the marking of regular cards, the speed class of UHS cards fits into the Latin letter U

Cards running on the high-speed UHS bus currently have only two speed classes:

  • Class 1 (U1)- from 10 MB/s;
  • Class 3 (U3)- from 30 MB/s.

Since the speed class designation uses the minimum entry value, theoretically a card of the second class may well be faster than a card of the fourth. Although, if this is the case, the manufacturer will most likely prefer to indicate this fact more explicitly.

Maximum speed

The speed class is quite enough for comparing cards when choosing, but some manufacturers, in addition to it, use the maximum speed in MB/s in the description, and more often than not even the write speed (which is always lower), but the read speed.

These are usually the results of synthetic tests under ideal conditions, which are unattainable in normal use. In practice, speed depends on many factors, so you should not rely on this characteristic.

Speed ​​multiplier

Another classification option is the speed multiplier, similar to the one used to indicate the read and write speed of optical discs. There are more than ten of them, from 6x to 633x.

The 1x multiplier is 150 KB/s, that is, the simplest 6x cards have a speed of 900 KB/s. The fastest cards can have a multiplier of 633x, which is 95 MB/s.

3. Objectives

Choose the right card taking into account specific tasks. The biggest and fastest is not always the best. In certain use cases, the volume and speed may be excessive.

When buying a card for a smartphone, capacity plays a bigger role than speed. The advantages of a large drive are obvious, but the advantages of high transfer speeds on a smartphone are practically not felt, since large files are rarely written and read there (unless you have a smartphone with 4K video support).

Cameras that shoot HD and 4K video are a completely different matter: both speed and volume are equally important here. For 4K video, camera manufacturers recommend using UHS U3 cards, for HD - regular Class 10 or at least Class 6.

For photos, many professionals prefer to use several smaller cards to minimize the risk of losing all the images in force majeure circumstances. As for speed, it all depends on the photo format. If you shoot in RAW, it makes sense to invest in microSDHC or microSDXC class UHS U1 and U3 - in this case they will reveal themselves fully.

4. Fakes


jcjgphotography/shutterstock.com

No matter how trivial it may sound, it is now easier than ever to buy a fake under the guise of original cards. Several years ago, SanDisk claimed that a third of SanDisk memory cards on the market were counterfeit. It is unlikely that the situation has changed much since then.

To avoid disappointment when purchasing, just use common sense. Refrain from buying from untrustworthy sellers, and beware of offers of “original” cards that are significantly lower than the official price.

Attackers have learned to fake packaging so well that sometimes it can be very difficult to distinguish it from the original. You can judge with complete confidence the authenticity of a particular card only after checking using special utilities:

  • H2testw- for Windows;

    • If you have already experienced the loss of important data due to a memory card failure for one reason or another, then when it comes to choosing, you will most likely prefer a more expensive card from a well-known brand than an affordable “no-name” one.

    In addition to greater reliability and safety of your data, with a branded card you will receive high speed and a guarantee (in some cases even lifetime).

    Now you know everything you need to know about SD cards. As you can see, there are many questions that you will have to answer before purchasing a card. It's probably a best idea to have different cards for different needs. This way you can take full advantage of the equipment without exposing your budget to unnecessary expenses.

Many users who do not have much experience with portable gadgets are wondering what MicroSD is.

MicroSD is one of the subtypes of SD cards (Secure Digital Memory Card). This card is a storage medium intended for use in portable equipment. For example, devices such as and video cameras are most often equipped with a slot for connecting SD or MicroSD cards.

The SD card format was developed based on the old MMC card format back in 1999 by Panasonic, SanDisk and Toshiba. The SD Card Association was later founded to organize efforts to improve and promote the SD format. However, MicroSD cards appeared only in 2004, when SanDisk introduced the TransFlash standard. And already in 2005, the TransFlash standard was officially approved by the SD Card Association under the name MicroSD.

MicroSD cards have ultra-compact dimensions (20×21.5×1.4 mm and weight 1 gram), allow you to store up to 32 gigabytes of data, and at the same time provide high operating speed. A device with similar characteristics was simply doomed to enormous popularity.

Scope of application of SD and MicroSD

There are three types of SD cards: regular SD cards, MiniSD and MicroSD cards

Ordinary SD cards are most often used in photos and cameras for storing footage. While MiniSD and MicroSD are used in more compact devices. Thus, most modern mobile phones, smartphones and communicators are equipped with a slot for connecting a MicroSD card. In this case, the MicroSD card is used for videos, music and programs.

In addition to being used in mobile technology, SD cards are increasingly used as a storage medium for larger equipment. For example, a large number of modern

Summary testing of 20 32 GB SDHC memory cards

Now, no matter what store you go to, there are a huge number of memory cards from various manufacturers on the shelves. They differ from each other in format, class and, ultimately, in the speed of reading and writing data. But how big is the difference in practice? This is what we will check in our new testing!

If you format the card using standard OS utilities or in a device that does not support the SDXC standard, it will end up with a different file system (for example, FAT32). The SD Association warns that the card will no longer be compatible with devices that support SDXC. Fortunately, for some card readers, cameras, etc. it is enough to update the driver or firmware.

⇡ Increase in speed: fast, faster, even faster!

Along with the capacity of memory cards, the data transfer speed also increased. In the early days of SD, it was measured in multipliers or “speeds.” One multiplier (or one “speed”) was equal to 150 KB/s - everything like CDs in their time. It’s just that such multipliers sometimes indicated the maximum access speed obtained under ideal conditions, be it reading or writing, and this is not the best option for the buyer. Therefore, the SD Associations decided to put an end to this disgrace, and in 2006 (SD Specifications V. 2.0), together with SDHC standard cards, four speed classes were approved for them: 0, 2, 4 and 6. Each class designated the minimum data transfer rate in decimal megabytes per second, both for reading and writing. Except zero class. This includes all cards released before the adoption of the specified specification, regardless of performance. A unified standard for marking memory cards was also approved: the number indicating the speed class was written inside the capital letter C.

Memory card speed classes

Alas, humanity is designed in such a way that it always lacks land, oil, minerals or memory card speeds. Therefore, in the next specification (SD Specifications V. 3.01 - the same one that describes SDXC cards), the 10th speed class was introduced, with a rating of 10 MB / s (again, in decimal format), and the UHS-I bus (Ultra High Speed, version 1), which could be used in SDHC and SDXC format cards. Using this bus increases the maximum theoretical data transfer rate to 104 MB/s (when the bus is supported by a card reader or other device) and does not entail any backward compatibility issues between new cards and older readers (provided that the latter support SDHC or SDXC formats).

On memory cards that support the UHS bus, you can find a mark in the form of the Roman numeral 1, and also a UHS bus speed marking - numbers 1 or 3 inscribed in a capital letter U. The first UHS class is equivalent to the usual tenth SDHC speed class (10 MB / s ), and the third speed class, as you might guess, should provide an access speed (sequential reading and writing) of at least 30 MB/s.

Then, in June 2011, the SD specification version 4.0 appeared, describing the UHS-II bus, which should increase the maximum throughput up to 312 MB / s. In addition, the use of the UHS-II bus provides for an increase in contacts on the card by eight pieces. Separately, I would like to note the preservation of backward compatibility between UHS-II and UHS-I cards.

The Roman numeral II is used to mark memory cards that support the UHS-II bus.

As of this writing, data transfer speeds of 312 MB/s are still fantastic. And there are very few memory cards themselves that support the UHS-II bus; they cost the same as a good SSD drive, and with a larger capacity. Take for example Panasonic Micro P2: capacity 32 or 64 GB, maximum sequential read speed - 2 Gbit/s. Price - about 11 or 16 thousand rubles, respectively.

Memory card with UHS-II bus

It turns out that over the 14 years of its existence, SD memory cards have undergone many changes and were divided into several formats. But only reading devices, but not cards, are backward compatible with previous formats (see diagram).

⇡ Memory card labeling options. How not to make mistakes when buying?

Now let's briefly summarize everything that was said above. At the time of writing this article, SD memory cards of two formats may be available on sale: SDHC and SDXC. They differ from each other in maximum capacity and file system. The maximum capacity of SDHC is 32 GB, and SDXC - 2 TB, although in reality it is very difficult to find an SDXC card with a capacity of more than 128 GB. We were able to find the “largest” card with a capacity of 256 GB only from Lexar. It costs $399 on Amazon, but is not found in Russian stores.

Before moving on to further selection of a memory card, it is worth figuring out what capacity you need. If it is more than 32 GB, then you should go for SDXC and check all devices in which you plan to use this card for compatibility with this standard. It is worth checking old card readers and cameras especially carefully, because modern equipment (if we are not talking about a laptop with Linux and a camera from three years ago) should not have any problems with SDXC (or rather, with the exFAT file system). If your camera does not support SDXC, then you should search the Internet for new firmware and a description of it - sometimes the manufacturer can add SDXC support in the new firmware. As, for example, this was done with the Pentax K-x camera.

So, speed. In order to determine the approximate data transfer speed of a memory card, you need to look at its speed class and support for the UHS-I or UHS-II bus.

On some memory cards from among those that took part in our summary testing, we also found not only the usual tenth class marking, but also the speed indicated in the “multipliers” - this is a normal, albeit rare phenomenon.

The best option would be the card that has an established write or read speed tested by the manufacturer on the packaging or front side. When purchasing such memory, you can be sure that the sequential read or write speed will be higher than the minimum acceptable level for class 10. And for very expensive memory cards (for example, SanDisk Extreme Pro), the sequential read and write speeds stated on the packaging can reach values ​​of 90 MB/s. But in practice, memory cards with the specified speed are more expensive than others, which is quite normal - you have to pay separately for fast and tested memory. In addition, sometimes there are markings like “up to 60 MB/s” without indicating what type of data transfer this speed refers to - reading or writing.

The image below shows examples of speed class designations on memory cards. OltraMax card: simply tenth class; Transcend card: class ten supporting UHS-I bus and UHS speed class one; SanDisk: Class 10, UHS-I, Class 1 UHS-I and claimed speed of 95 MB/s.

⇡ Test participants, specifications

Our summary testing involves 20 different memory cards from different manufacturers - popular and not so popular. Among them there are both copies without a declared data transfer speed (but not lower than class 10), and cards with data transfer speeds of up to 90 MB/s. If the speed was indicated on the card packaging, but it was not written what it refers to (reading or writing), then so much the worse for the cunning manufacturer. In our table, we recorded this speed in the “read” and “write” cells labeled “total”.

Before moving on to the description of our experimental subjects, I would like to remind you about the cost of memory cards. We have indicated two prices in the table. The first is the average retail price taken from 3DNews, and the second is obtained using other sources. Since the prices are average, the cards we selected can be found in Moscow online stores even cheaper than indicated in the table. Everything will depend on the total number of offers on the market, the relevance of a particular memory card and, quite likely, on fluctuations in the dollar exchange rate in recent months.

⇡ Transcend Premium TS32GSDHC10, Premium 300x TS32GSDU1 and Ultimate 600x TS32GSDHC10U1

The trio from Transcend can serve as another illustration of the description of memory card labeling. The youngest card (Premium TS32GSDHC10) only indicates the 10th speed class, but the other two (Premium 300x TS32GSDU1 and Ultimate 600x TS32GSDHC10U1) indicate the 10th general and first UHS class, as well as speed in “multipliers” that are almost equal to the speeds in MB/s indicated on the packaging. This is roughly what manufacturers do when they want to make their cards more attractive to the buyer, because “300x” and “600x” at first glance look “more” than 43.5 or 87.9 MB/s, respectively.

Although the fastest memory card, Transcend Ultimate 600x TS32GSDHC10U1, has one advantage over other test participants. The manufacturer stated that it uses MLC memory, while on the packaging (and in the specifications) of other cards it is not possible to find a word about the chips used. However, the MLC (Multi-Level Cell) marking, by definition, can designate cells with both two and three (also called TLC) charge levels. Both options are used in memory cards.

⇡ Kingston Ultra SD10V/32GB, Elite SD10G3/32GB and Ultimate SDA10/32GB

There will also be three memory cards from Kingston, another well-known storage manufacturer, in our testing. The youngest card, Kingston SD10V/32GB, only has speed class ten, but other cards, Kingston Elite SD10G3/32GB and Ultimate SDA10/32GB, have stated read speeds of 30 and 60 MB/s, respectively. For Kingston Ultimate and 35 MB/s the recording speed is also stated.

⇡ SanDisk Ultra SDSDU-032G-U46, Extreme SDSDXS-032G-X46 and Extreme Pro SDSDXPA-032G-X46

SanDisk cards are a pleasant exception in our test. The thing is that all three cards from this company we use have a maximum access speed indicated. The youngest card, SanDisk Ultra (SDSDU-032G-U46), has 30 MB/s for sequential read, while SanDisk Extreme Pro has 95 and 90 MB/s for sequential read and write, respectively.

⇡ ADATA ASDH32GCL10-R, ASDH32GUICL10-R and ASDH32GUI1CL10-R

ADATA is a manufacturer of storage devices of various types and purposes. The company's product line includes RAM, external hard drives, solid state drives and SD cards. We took the last three devices from ADATA for testing.

Before us is an almost standard set of three cards: the simplest ADATA ASDH32GCL10-R class 10 without specifying access speeds and two more complex cards. Thus, the ADATA ASDH32GUICL10-R has an overall speed of up to 30 MB/s, and the most advanced one, ADATA ASDH32GUI1CL10-R, has a total speed of 95 MB/s for sequential reading and 45 MB/s for writing.

⇡ Silicon Power SP032GBSDH010V10, Elite SP032GBSDHAU1V10 and Superior SP032GBSDHCU1V10

Silicon Power can be called a direct competitor of ADATA, because on the official website of this company you can find almost the same range of products as on the website of the previous manufacturer.

The cheapest Silicon Power card - SP032GBSDH010V10 - only has speed class 10, but other models have speeds of 40 and 15 MB/s (Silicon Power Elite SP032GBSDHAU1V10), as well as 90/45 MB/s (Silicon Power Superior SP032GBSDHCU1V10) for reading and writing respectively.

⇡ OltraMax OM032GSDHC10, OM032GSDHC10UHS-1 and OM032GSDHC10UHS-1 95 MB/s*

The OltraMax company, unlike all other test participants, is practically unknown to the average consumer. But inside the packages of two fast OltraMax cards it is written that the company uses Samsung components - this is good advertising for the card manufacturer. The only pity is that in order to see such advertising, you need to buy a memory card and open the package.

The OltraMax trio is almost no different from the previous trios. The simplest and cheapest card from this manufacturer, OltraMax OM032GSDHC10, is marked only with class 10; the average memory card, OltraMax OM032GSDHC10UHS-1, also cannot boast of any marks other than class 10 and UHS-I. But the coolest card, OltraMax OM032GSDHC10UHS-1 95 MB/s*, promises speeds of about 95 MB/s, which is very interesting.

The next two cards are a little out of the general list. We received only one class 10 drive from Qumo for testing. And the Toshiba FlashAir SD-F32AIR(BL8) stands out because it is capable of providing access to content via Wi-Fi.

Memory cards with Wi-Fi have long been no longer considered something unusual or innovative - many manufacturers have such models, but their small variety hints at their modest popularity. Judging by the characteristics, you shouldn’t expect high speeds from the Toshiba FlashAir SD-F32AIR (BL8) - this card doesn’t even support the UHS-I memory bus. But it has Wi-Fi and even the ability to distribute wireless Internet if you add a name to the card settings and access password to another network
