This USB drive is advertised as supporting USB 3. Sure, it probably does, but the write speed is the worst I've seen. Copying files to the drive fluctuates between 0 kB/s and 20 MB/s. I've tried three different USB 3 ports in two different PCs and same result. I bought it because I need to transfer 234 GiB of files, and it will have taken over 48 hours to copy the files!
Also, the advertised capacity is a lie. It's of course not 256 GiB, but it's also not 244 GiB. It's 230 GiB, which is slightly less than the size I needed.
