If you're going to go the route of a CF card, and you're not doing a 
write-only filesystem with a RAM disk overlay, you would be well advised 
to format it with something like UBIFS.  It is specifically designed to 
provide software wear leveling and block re-allocation for raw NAND 
flash devices with no SSD disk controller to perform that task for you.
