A useless product, its not worth the money.

If you use it as a non-system disk, then the tests are rather poor, but not so terrible. Extremely rarely, probably 1 time out of 25 tests, it gave out just the same extremely low write speed, about 50-100. Once, even copying files got stuck.
The last screenshot shows how a 6 GB file is copied. At first, the speed is 380, but after 6 seconds it already drops to 52-38 and somewhere on average by 50, sometimes even by 40, and copying from one SSD folder to another is in progress.
Health 100%, AHCI enabled. They say ating the SSD itself helps, but the firmware can not be found, and the official program writes that the ate is not required.

Pros

Good reading speed within 540-480. It helped to raise fps and its stability somewhat, where games constantly pulled the hard drive due to a lack of video card memory. Sorting small files of 20 MB or less by date in the amount of 15k pieces on the HDD in one folder took 4 minutes 55 seconds, on the SSD it was just 55 seconds, but on the SSD with Windows running from it, sorting takes 15 seconds.

Cons

The write speed is about 50 mb / s when the cache is clogged, apparently, it seems to me. A month or so was used for games, but one fine day I decided to put another Win 10 on it. I opened CrystalDiskMark 6 and instead of the usual 500/380, with over 60% occupancy, I saw 500/50. After starting the system, it can pass 2-3 more tests at an acceptable speed, but after that it rolls down to 50 again.
