Check the lexar sport http://www.lexar.com/jumpdrive/jd_sport.html

I think this is the one Schwert is refering too.
Mine has been through the wash several times and is still going strong. We used to use the Sony's but we had 2 of 12 go bad. We have 8 lexar sports and none have gone bad. Forget about the encryption/thumbprint/snakeoil drives. They are not worth the hassle, and are really just a gimick. Anything that sensitive/important should not use that type of encryption anyway. If you do care, PM me and I'll point you in the right direction. Anyway, I have heard very good things about the SANDisk drives.
