I'm thinking of using a USB flash disk in place of a hard disk on a rarely used server. This seems to be widely touted as a possibility. But on the other hand I have been warned by several people that the USB drive will get exhausted quite soon. I've been unable to find any hard figures on this. Also, I wonder if there is any reasonably standard way of organising Fedora/Linux so that the "hard drive" is written to as little as possible, presumably using RAM instead.
