This is absolutely the most durable USB Drive that Samsung makes. You won't break this drive, ever. Additionally, it is as wide as the USB-A port it plugs into, meaning it will not block any other ports when connected to your computer. Finally, it has a hole so this can be attached to a keychain. While the write speeds seemed slow in my example below, this is due to the size tested. at 64GB, it is 4 x smaller than the other Samsung drives. If this were a 256GB, I would expect it to perform identically to the other Samsung drives.
