Alternatively, the concern is that the FAT/inode table or the like is where the most wear will occur - perhaps concentrate there? (i.e., do a journelled FS like reiserfs with a fast update? Do any USB keys do some kind of write minimisation in the controller? - no change in the data/no write? - seems a logical way to extend the life?
