To satisfy the needs of Samsung smartphone fans, the Korean company has expanded its already rich range of products with memory cards. The EVO Plus fully lives up to its name, perhaps being the most interesting microSD card in the line, combining sprint speed, a bandolier of additional functions and a democratic price.

Samsung EVO Plus belongs to the U3 class, the fastest among microSD cards, so it has no problems recording 4K video with high bitrate, shooting in RAW and other tasks where it is important to quickly "turn" large volumes of data.

According to the passport data, the read speed is about 100 Mbps, the write is at the level of 60 Mbps. At the same time, the minimum steady rate of information exchange is 30 Mbps. You can copy a 3 GB video to a compatible device in about 38 seconds. This is one of the best speed indicators on the market. In general, the 64 GB EVO Plus can accommodate 3 GB of 4K video and over 14K photos.

All kinds of protection systems in service with the model allow you to maintain the performance of the data carrier even when the device with which the flash drive was equipped fails. Judge for yourself, she is not afraid of sea water (when submerged for less than 72 hours), nor electromagnetic waves, nor X-rays, nor strong temperature differences (from -25 to 85 degrees Celsius).

Goodram focuses the M3AA card primarily on owners of GoPro-type action cameras, as it is more durable than the average memory card. This durability is manifested in a 10-fold increased cycle of erasing and writing data to the card. In addition, the card is designed to work in high-intensity mode, when recording is conducted almost 24/7 (as, for example, in DVRs). However, forTV with 4K video support or modern camera phones that shoot in 4K and RAW, a combination of high speed and reliability is unlikely to be superfluous.

The card allows you to record information at a speed of up to 90 Mbps. The reading speed can reach 95 Mbps. At least, such figures are given by the manufacturing company in the "passport" of the model and, importantly, they are fully confirmed in fact. The UHS-I U3 and V30 speed classes assigned to the flash drive report the possibility of operating large data arrays without speed subsidence below 30 Mbps.

Plus, Goodram claims about the increased reliability of the card, which ensures the security of recorded information. Firstly, we are talking about the use of MLC memory, for which the manufacturer gives a lifetime warranty. Secondly, the operating temperature range is from 0 to 70 degrees Celsius, and the recommended storage temperature is from -25 to +85 °C.

Well, the price with all this turned out to be very democratic.

The Canvas Go line! in the model range of microSD cards from Kingston, it is positioned for action cameras, drones and DVRs. However, she is also friends with smartphones and SLR cameras. The gain in serial shooting in RAW compared to a conventional U1 class memory card is 2-3 frames before the buffer is filled. And the buffer itself is released a couple of seconds faster.

According to the Canvas Go passport! It belongs to the U3 class and boasts the following speed indicators: up to 90 Mbps when reading, and up to 45 Mbps when writing. And this is a strange moment. Most microSD cards of the U3 class have a minimal difference in the speed of writing and reading. Here we have a gap of two times. But this is not surprising, but the fact that in synthetic tests Canvas Go! shows the recording speed above the passport. In H2testw we have all 83 Mbps, in ATTO Disk Benchmark 62 Mbps.

However, all this is noticeable more in test utilities, rather than in real operation. In general, we get a fairly fast card that easily overtakes U1 class cards and has increased reliability. The manufacturer promises operating temperatures from -25 to 85 degrees Celsius, protection from moisture, radiation and vibrations. In addition, the manufacturing company is so confident in the reliability of its offspring that it was not afraid to provide a lifetime warranty for the product, albeit limited.

 
Class A2, high reading speed, not afraid of water and radiation, resistant to temperature changes, proprietary software.

SanDisk Extreme V30 A2 is one of the first memory cards in the arsenal of SanDisk, which corresponds to Class A2 (note: it has a high read and write IOPS) and provides a high volume of I/O operations every second. This makes it an perfect option for installation on board a smartphone, where you need to quickly interact with applications that perform a lot of read/ write operations. Well, do not forget about the resource-intensive recording in 4K.

According to the passport, the SanDisk Extreme V30 A2 is one of the fastest mircoSD cards on the market: the read speed is 160 Mbps, the write speed is kept at a brisk 90 Mbps. And if in the first case everything is ambiguous (in synthetic tests, the reading fluctuates around 100 – 120 MB /s), then the speed of writing files to memory completely coincides with the figure prescribed in the technical documentation. Here we have full compliance with the UHS-I U3 and V30 specifications.

Like other modern memory cards, the SanDisk Extreme V30 A2 is shock-resistant and waterproof, works at a wide temperature range and is protected from X-rays.

Plus, along with the flash drive, the user receives a nice bonus in the form of a set of software from SanDisk. We are talking about the Memory Zone utility for backing up data to Android devices, and RescuePRO for recovering files lost from a USB flash drive.

 
High reading speed, not afraid of water and radiation, resistant to temperature changes, ACCORDING to Transcend RecoveRx.
 
 
There is no adapter included.
 

Memory modules are the backbone of the products of the Taiwanese company Transcend. One of the most significant items of brand revenue is external data storage. The microSD model from the 500S series will serve as an excellent example of a suitable card for modern mobile devices.

The card complies with both the UHS Speed Class 3 (U3) standard and the UHS Video Speed Class 30 (V30) requirements for recording 4K Ultra HD video, providing read and write speeds of up to 95 and 60 Mbps, respectively. In addition, the older 128 GB model can also be a replacement for the internal memory of your gadget — it fully complies with the Application Performance Class standard, which means fast and uninterrupted operation of your applications installed on the memory card.

As a bonus, we have Transcend RecoveRx software on board to search for and recover lost data. The list of advantages of the model continues with the all-protected design (the drive is not afraid of diving under water and static voltage, and is also characterized by shock resistance and resistance to X-rays). It's just a pity that there is no adapter for the "adult" SD size in the kit, which allows you to operate the data carrier on board glass and mirrorless photographic equipment. It's not difficult to buy it, but usually when you buy a microSD card (and even such an expensive one), you expect that the adapter will be included.

Against the background of all this, the only disadvantage seems to be the price, which is somewhat high in comparison with competitors having the same characteristics.
