SanDisk Ultra UHS-I 200 GB
The new SanDisk Ultra series memory card is a kind of flagship among microSD cards. At the moment, this is the only card of this form factor that has a volume of 200 GB. Not only has such an indicator been recently only available for full-length SD and CF cards, the new SanDisk Ultra also supports data transfer via a high-speed UHS-I bus for fast exchange with a PC and for streaming high-definition video. In the review we will tell about the tests of the new card in various conditions and about the pitfalls that flash drive buyers may encounter.

Well, the speed performance of the memory card in the benchmark is quite consistent and even ahead of the stated, but it would be nice to check the performance in real conditions. The first test was to write to the card file with a capacity of 15.7 GB, which took 18 minutes 4 seconds. It is easy to calculate that the average write speed at the same time was 15.6 MB / s. In this and subsequent tests, we took the file size in bytes and translated it into megabytes, given that one megabyte is equal to one million bytes, because, as mentioned above, it is these proportions that are used in the SD standard. In addition, a solid-state drive (SSD) was used to transfer files from and to the computer so that the results of the tests were not affected by the relatively slow performance of the hard disk drive (HDD).
Transferring the same file from a memory card to an SSD in a computer took only 3 minutes 23 seconds, which gives an average speed of 83.2 MB / s. Both values are lower in comparison with the results of CrystalDiskMark, but synthetic tests are called that because they are conducted under ideal conditions and often do not quite correspond to daily work.
The previous test reflects well the case when a memory card is used to record video. But when using a memory card to store snapshots, the conditions are different, so it is important to know how it will cope with transferring a large number of small files (on average, 6 MB). Writing photos with a total volume of 2 GB to the memory card took 2 minutes 55 seconds, which gives a speed of 12.6 MB / s. It is expected that this value is slightly lower compared to recording a single file.
But the return transfer took only 30 seconds at a speed of 73.6 MB / s – an excellent result.
Due to its uniqueness, today the range of applications for the SanDisk Ultra 200 GB memory card is as wide as possible. First of all, such a card is needed by those who write or store large amounts of data. Despite the fact that the UHS-I bus is not the fastest, its capabilities may not be enough except for those who record Ultra HD video with ultra-high bitrate.
But for ordinary tasks, such as recording Full HD video or professional photography, the capabilities of this card are more than enough. If the price does not deter you, SanDisk Ultra can also be used in a smartphone or tablet: the size of the memory card is enough for storing a full-fledged video library in the device, not to mention the possibility not to transfer photos and videos to a computer for a long time if you shoot a lot.
