The Kingston DataTraveler is completely reliable (and this is certainly the most important when 'Data traveln'). Have it on 4 computers alternately in use (WinXP and W2K, each problem-automatic detection). He has never let me down. While I am not with the stopwatch next, but place the following Geschwindigskeitsverhalten fixed (which certainly depends on the PC and not the DataTraveler): Send large files: fast via USB2.0 and USB1.1 slightly slower than (certainly no different than expected) But: Small files (a few KB big): very fast over USB1.1, USB2.0 extremely slowly (yes, read that right). Another tip: The DataTraveler is formatted for FAT, which makes little sense. Therefore, he should be immediately formatted before first use as FAT32 (without any problems). As I said, I'm very happy with it.
