boring but important:
I need to back up about 20MB of important research project work.
At the moment I'm backing up (using Backup 1) to CD-RW about twice a week.
For such a small amount of data it's a fairly slow/inconvenient process. So I thought about a USB flash memory pen. Are such devices suitable for backing up important data, or are they more for portability. Should I stick to cdrw?
