How rough is rough? Survivor tough enough? Or is a Corsair Voyager good enough?

Mine advise would be not to take those super thin drives, without the metal guide around it. (brakes off the plastic thingy in the gate)

USB 3.0 is very nice if you transfer lots of data. Much quicker, but your computer need USB 3.0 to get those speeds.

Don't get models with separate caps, you loose them...
