Flash memory stress test

My 128 MB Rundisk 2.0 flash drive somehow chose to remain in the pocket of my shirt when it was put for wash. Needless to say, it spun for over 1 hour 15 minutes in soapy dirty water, and I noticed it along with some unidentifiable shredded pieces of paper when I was hanging it out to dry.
Surprisingly though, it still manages to work just like before. I've dropped the drive multiple times from over 4.5 feet before, and put it inside my bag where it lay between all sorts of other hard non-electronic devices and managed rough handling that even my bag couldn't. But this, really, is some sort of a benchmark that it has managed to come clear of.
