I bought the 256GB version of the drive, and I am extremely disappointed by its absolutely horrid performance. Try transferring many small files and you'll run into the slowest transfer speeds you've ever seen. We're talking less than 10KB/second here! Solid advice: Stay far away from this overpriced literal garbage. And before you say "But maybe your computer doesn't support UASP!", I can tell you that I've tried it in many brand spanking new PCs and it reacts in the exact same say on all of them.
