Great for that hidden archive
I have only had it for 1 day. I made mine bootable and put windows xp on it. I will not change its contents ever again. It is strictly a windows xp installation tool. I got around 16MB/sec read and 4.8MB/write (sequential-large file). 1-3/16th long by 15/32nds wide and 3/32nds tall.
It looks cool, simple and small, no moving parts, its inexpensive; You could step on it, and it would probably not sustain any damage; FCC and CE certified
Might not withstand a lot of use considering the 4 gold plated contacts are very thin and are etched on a printed circuit board; It looks as if it would break if bended too much
