Before being sent to store shelves , the flash drive is tested for water resistance, shock resistance, resistance to x-rays and static electricity. On paper, the memory card's endurance is backed up by a lifetime limited warranty, further confirming the drive's longevity.

In terms of speed indicators of data exchange, the model belongs to the basic segment of microSD cards. The user has the right to count on reading information from a flash drive at a rate of up to 100 MB / m and writing files at a speed of about 25 MB / s. These numbers are enough to record Full HD video and take pictures. For shooting videos in 4K frame resolution, it is better to look at the models more quickly. The card belongs to the 10th speed class of drives and is marked with the video recording index V10 - when writing data to a memory card, the speed is guaranteed not to drop below 10 MB / s.

In the slot of A-Data Premier microSD UHS-I Class 10 smartphones and tablets, it can be used not only to store permanent information such as photo and video files, but also to install mobile programs. IOPS (I/O operations per second) in read mode and 500 IOPS in write mode. Users can launch applications and perform related operations comfortably. Also, the built-in algorithms for automatic error correction EEC are defined in the positive properties of the drive. Out of the box, the flash drive is equipped with an adapter for a full-size SD format.

The Team Group Elite microSDXC A1 V30 UHS I U3 model was created specifically for mobile devices and 4K video recording. And in these roles, the memory card feels like a fish in water.

Sharpness of the flash drive for joint work with smartphones and tablets is manifested in the class designation for A1 applications. This means that it is allowed to install mobile programs on the card and calmly perform operations related to them. Also, the drive is designed to store permanent information: photos, videos, documents, etc.

Classes UHS-I U3 and V30 indicate the minimum speed for writing data to a memory card, which does not fall below 30 MB / s. As a rule, this is more than enough for shooting video in ultra-high definition 4K. And not only on a smartphone, but also on a serious camera - a card is inserted into the slot of the corresponding equipment for video recording using an SD adapter.

The model has been tested to maintain performance at high and low ambient temperatures, and it also boasts moisture resistance, shock resistance and resistance to x-rays. A pleasant bonus from the manufacturer is a lifetime limited warranty on the product.

Kingston Canvas Go! Plus is assigned to the strong medium segment of microSD storage. It gives good speed indicators for reading and writing files, has an indestructible character and a lifetime warranty. But let's talk about everything in order.

The memory card is marked with several important markings. The inscription "U3" on it indicates support for the UHS-I Class 3 bus with a guaranteed linear write speed of at least 30 MB / s. Approximately the same meaning is embedded in the symbolism "V30", which is a video recording class for the drive. The performance level of a flash drive when used in conjunction with a smartphone or tablet is labeled A2 - models with this tab speed up running applications.

Kingston microSDXC Canvas Go! Plus fully complies with the speed performance in read mode (up to 170 MB / s), and when writing data, the model demonstrates superpowers - instead of the declared 90 MB / s, it easily “accelerates” to 120-130 MB / s. With such characteristics, the drive will fit for shooting 4K video with a frame rate of 60 or even 120 fps. Moreover, the flash drive will also pull 8K video with a frame rate of 30 fps.

The model has a special endurance. It's no joke, the flash drive captivates with water resistance, shock resistance, vibration resistance, X-ray protection, as well as a wide operating temperature range from -25 ° C to +85 ° C. As proof of its indestructible properties, Kingston kindly provides a lifetime warranty on the product.

Fast, capacious and reliable flash drive GOODRAM microSDXC IRDM V30 UHS I U3 will become a faithful companion for a smartphone, action camera or even an "adult" camera (using the supplied adapter to SD-size).

The IRDM series of cards provides high performance for 4K video recording, burst photography and handling large data sets in general. The model under consideration was no exception to the rule. It uses a UHS-I interface with speed class U3. And the video recording class of the V30 drive guarantees a minimum continuous write speed of at least 30 MB / s.

Speed indicators for reading data from the card are declared at a rate of up to 100 MB / s, writing information to it - up to 70 MB / s. In real practice, these values are fully respected. The flash drive performs well in the slot of cameras and car recorders when shooting video in resolution up to 4K. She shoots “ordinary” videos in Full HD frame format without the slightest hitch.

The memory card is not afraid of bumps and drops, is resistant to X-rays and has moisture protection. The best confirmation of the high reliability of a microSD drive is a lifetime product warranty directly from GOODRAM. This is indirect evidence that the manufacturer is completely confident in the quality of the flash drive.

The SanDisk Extreme Pro V30 A2 microSDXC UHS-I U3 is one of the fastest microSD drives on the market today. How are things really? Let's figure it out.

For the model , a very high reading speed of information up to 170 MB / s is indicated. In reality, it rarely exceeds 100 MB / s. The same can be said about the speed of writing data to a USB flash drive (90 MB / s "on paper") - in fact, files are written at a slower pace. However, one important “but” pops up here - the declared data exchange rates are achieved using a proprietary SanDisk card reader. Without it, you have to be content with the more modest work of the drive.

The memory card has been assigned a video recording class of V30, which allows you to record 4K video on it. In addition, the model is marked with a class mark for A2 applications. The drive performs well when running mobile games and programs installed directly on the card. The model performs up to 4000 input-output operations per second (IOPS) when reading data and about 2000 IOPS in write mode.

SanDisk Extreme Pro V30 A2 microSDXC UHS-I U3 is fully protected from all kinds of adversity: the flash drive is unaffected by high and low temperatures, it is resistant to shocks and falls, and has X-ray protection. The icing on the cake is a lifetime warranty on the memory card as a symbol of high reliability and durability of the data drive.
