If you use ext2, ext3, or some similar block and Inode based file system on a 
flash device with no wear-levelling layer in between then you are doing 
everything wrong.

Some (most?) of the flash hardware that looks like an ATA disk or similar has 
it's own wear levelling, so although ext2/ext3 writes the same Inode block 
repeatedly it's really going to different parts of the storage.  Even so 
mounting noatime is the best thing to do.
