I got it along with some other JetFlash because the JetFlash 770 32 GB USB 3.0 is the only flash drive of mine that lasted over five years. From the benchmarks, it seems to be the same device in a different case, so I will give it exactly the same rating. On the other hand, many stores sell it as USB 3.1, which may not actually be true. Unfortunately, I did not keep the packaging, and there is nothing written on the device.
