Here is a USB3 key that is not even worthy of USB2. Not having known the 1st version of USB, this key gives me (unfortunately) a little insight. Indeed, 3.6 Gb load in just over 18 'holds the record, USB 2 in my possession do in less than 4'. Using many years of brand Kingston keys, I do not believe that it could be an authentic version, from asia, I confess to have big doubts about this. I thought that ordering through Amazon were to avoid these problems, I am very disappointed!
