I agree redundancy is probably the shortest path to a reliable drive. I have two on my keychain, a Verbatim Store n Go, and a Verbatim Tuff n Tiny, like this - http://www.amazon.com/Verbatim-TUFF-Driv...197&sr=1-1. I've been impressed with the Tuff n Tiny, not only is it very small, there are no caps or moving parts, its literally the most convenient thumb drive I use. I keep an OS image on it, also store docs and other things I need. I've only had it about a month so I can't rate it's durability, but others have reported that it stands up to a beating well.
