Every cell of flash memory is good for a certain number of writes before that cell becomes effectively read-only. If your fs is read-write, you don't have much control over where the next write is going to happen. A wear-levelling flash controller will spread all the writes around so that the cells age somewhat concurrently, while dumb flash (most CF cards) have there flash mapped somewhat directly to the OS's LBA map, and will happily write to the same cells over and over, greatly reducing the life of said cells, and thus the usable life of the unit as a whole.
