Performance-wise, nothing to say to use with transfer rates consistent with those announced, in the order of 80 MB / s on my computer to USB 3.0. MO 700 files take a few seconds to move from one medium to another. In USB 2.0, performance is also the rendezvous and files 700 MB take less than a minute from the PC to the key (27.5 MB / s) and are even faster in the other direction. Transfer photos, with a total file of the same weight, I have hardly seen a difference (a slower hair) either USB 3.0 or 2.0. Obviously, such performance is to qualify as another computer, only USB 2.0 is more recent but less powerful, transfers are a bit slower but still faster than my other USB 2.0 keys.
In summary, the key is entirely consistent with his description and it combines high capacity and speed in a small format, all I was looking for; I recommend!
