Corsair Voyager USB Flash Survivor 32GB USB 3.0 (CMFSV3-32GB) (Personal Computers)
This is a great item, ok I'll never swim 2500 meters (even less with my USB drive to verify that it works), but at least when I knocked it does not break (and yes, I'm not good with USB ...) In terms of speed, nothing to say no more effective it is.
