I bought a set of these disks to deliver scanned data (lots of small files) - in this case the disks write very slowly (around 1.25MB/s ). ). If you don't care about write speeds, go for these (I've had no other issues), but if you value your time I'd recommend paying a bit more for drives that actually run at USB 3.0 speeds.
