I bought the 256GB version after reading many reviews about the 128GB drive, most of which were about a free product and I was clearly wrong assuming that decent speeds would go a bigger drive. . It turns out that the 256GB version uses slower memory chips and outperforms at 105MB/s read and 30MB/s write. Actual sequential write speeds are around 25MB/s, which is very low for 2021. Further thoughts: The drive looks ok, but due to the thin plastic it feels cheap in the hand and stays relatively cold during prolonged writing. Long-term reliability is a big issue, so I wouldn't rely on it storing any meaningful data. Overall I'd give it a 2.5/5, the drive delivers what it promises in terms of capacity and no more. It's better to spend 2-5 dollars more and buy something faster and better. EDIT on 06/28/2021 several times when copying large files (BD rips over 40 GB), the file could not be successfully copied to discs, the Windows 10 copy dialog closed in the process and the file did not appear on the disc because if there was some kind of error records, but no error message appeared. I lower my rating to 1/5.
