Data safety in a compact bottle: TOP 5 microSD cards

SanDisk Ultra microSD UHS-I 32 GB Price from 199 up to 649 ₴ →

SanDisk is one of the most famous brands in the field of compact storage of information, which has representatives in its lineup for every taste and low-cost. The 32 GB SDHC flash drive belongs to the middle class, with excellent workmanship, high data security and a very attractive price tag.

The memory card is designed for installation in compatible mobile phones, DVRs, cameras and other electronic gadgets. It belongs to the 10th speed class, which guarantees a stable data recording speed at values not lower than 10 Mb / s and eliminates frame drops from the video sequence when recording FullHD video. Strictly speaking, the maximum recording speed is not very different from the guaranteed rate and in most cases is in the range of 10-15 Mb / s. Reading is traditionally faster, but far from the declared figure of 80 Mb / s - at speeds up to 35-40 Mb / s.

Some users note quite successful operation of a flash drive paired with action cameras capable of recording 4K video. But if you're serious about filming ultra-high-definition videos, SanDisk's lineup has better-adapted specimens, such as the SanDisk Extreme Pro microSD UHS-I 64 GB .

According to the manufacturer, the SanDisk Ultra series of memory cards is made in a shock-resistant and waterproof design. In addition, she is not afraid of vibrations and x-rays. The drive has a 10 year warranty. The Ultra line includes 8GB, 16GB, 32GB, 64GB, 128GB and 200GB tank sizes.

Kingston microSD UHS-I U3 32 GB

The possibilities of a memory card manufactured by Kingston are immediately hinted at by its packaging, on which the simple abbreviation "4K" is applied.

The miniature dimensions allow using the drive when shooting ultra-high resolution video using a smartphone or action camera (for example, GoPro HERO4 Black Edition ), and the bundled microSD-SD adapter does not exclude the ability to insert a memory card into an adult photo or video camera. In the course of testing the flash drive, the specialists of the Kaddr.com resource revealed that it feels confident in the mirrorless port Panasonic DMC-G7 kit 14-42 Price from 22 899 up to 32 533 ₴, on which videos are written at a resolution of 3840x2160 pixels with a bit rate of up to 100 Mbps.

Out of the box, it is stated that the speed of reading a memory card should reach 90 Mb / s, and writing - 80 Mb / s. In fact, the same values are obtained in practice: 82 Mb / s and 75 Mb / s, respectively. The speed of data exchange sags only in the case of processing large amounts of information, including many small files (up to 1 Mb in size). It's a sin not to mention the support for the high-speed UHS-I Class 3 bus, which guarantees the recording of information at a speed of at least 30 Mb / s.

A nice addition to the capabilities of the drive is its all-around protection - the memory card is not afraid of drops, water, vibrations and X-rays, and is also capable of operating in a wide temperature range(from -25°С to +85°С).

An important nuance. By default, microSDHC memory cards have the FAT32 file system, the maximum file size of which is limited to 4 GB (this is only enough for 5 minutes of continuous recording of 4K video with a frame rate of 25 fps and a bit rate of 100 Mbps). In order for the drive to record 4K videos at normal length, it must be formatted in another format (NTFS or exFAT).

Silicon Power Elite Color microSD UHS-1 Class 10 64 GB

Elite series flash drives from Taiwanese company Silicon Power are positioned as solutions for photographers, videographers and mobile gamers.

The name of the memory card contains the prefix "Color", which indicates the bright and colorful color of the drive. The advantage of a non-standard appearance is that the flash drive is easily conspicuous and will not get lost among its own kind. But the adapter for the usual SD-format is made in traditional black.

The manufacturer claims a maximum data transfer rate between the drive and a compatible device at 85 Mb/s. The real reading speed does not reach this indicator and reaches a value of 45 Mb / s. Recording is much slower: the minimum speed is guaranteed at a level of at least 10 Mb / s, and the maximum is limited to 15-20 Mb / s. In fact, support for the high-speed UHS-I bus is observed only on paper, because. the card has typical high-speed operating modes of a class 10 drive.

The microSD drive confidently copes with recording videos in FullHD resolution, with burst photography of heavy RAW files, as well as with turning games and applications on a smartphone or tablet. In addition, he wears a very affordable price tag, which will certainly appeal to most users.

Transcend Premium 300X microSD UHS-I 64 GB

The Taiwanese company Transcend indicates the speed characteristics of a flash drive in the old fashioned way - in the form of a multiplier of 300x, where the minimum CD playback speed (150 kB / s) acts as an "X". Through simple mathematical calculations, it is possible to find out that the maximum data exchange rate can reach 45 Mb / s.

In practice, the reading speed reaches the maximum value only when working with several small files. Often it fluctuates between 20-25 Mb / s. The data recording speed is even less - 15-20 Mb / s, which coincides with the declared value from the manufacturer (20 Mb / s). The card belongs to the 10th class, which is confirmed by the minimum guaranteed write speed of 10 Mb / s.

Despite the declared support for the UHS-I high-speed data bus, the memory card is more focused on interaction with portable devices that do not require high speed characteristics. She will cope with the work in a low-cost DVR and will feel good in a smartphone. But using it for burst photography or recording high-resolution video with a camera is not recommended. For these purposes, there are faster models of drives.

The card is able to recognize and correct errors when copying data, thus ensuring the reliable safety of information. And even in defective copies, which are more common than we would like, the data remains intact - the flash drive often fails, blocking access to writing and erasing information, while leaving access to copying it. On top of that, in terms of price-volume ratio, the drive is one of the most attractive options on the market.

SanDisk Extreme Pro microSD UHS-I 64 GB

Drives under the SanDisk brand have always stood out for their excellent workmanship and high reliability. The 64 GB Extreme Pro is no exception to the rule.

According to the results of testing the memory card, which was conducted by the famous magazine Chip, the flash drive took first place among more than 70 peers. Its declared speed characteristics (reading information at the level of 95 Mb / s, and writing - 90 Mb / s) fully correspond to the real state of affairs, differing from it by just a couple of megabytes.

The card supports the UHS-I Class 3 high-speed data transfer interface, which indicates a minimum sustained write speed of at least 30 Mbps. These numbers are more than enough for serious tasks, whether it's a long series of photos in maximum quality or recording QuadHD video.

A flash drive can be safely called an perfect choice for action cameras and quadcopters. And in the case of using the bundled microSD-SD adapter, it is also for cameras capable of recording 4K content with a high bitrate. In a mobile phone, she will not show herself to the fullest, but she will completely forget about any lags or slowdowns.

The drive comes with an annual subscription to a data recovery programme. By the way, losing them is not so easy, given that the card is reliably protected from shock, moisture and X-rays. Only the high price, which is more than compensated by the capabilities of the memory card, can moderate the ardor from its acquisition.
