I’ve noticed many EDC’s pictured here include a 128 MB USB drive on the key ring. Given how many magnetic fields we’re exposed to anymore, does anybody worry about their data being lost? I’m too cheap and distrustful to pay for remote server backup, but I’m considering different ways to back up my personal data in case of home disasters that would destroy my computer and peripherals. My prejudice is to back up to CD’s and store them in the safe deposit box, with relatives, and with my bug-out stuff. As far as I know, CD-ROM’s are not subject to corruption by strong magnetic fields like I assume the USB drives are.

How do people use or like the little USB drives? I saw a Victorinox SAK packaged with one at Target last night, which is what prompted my question.
