(Bits or bytes?)

Ah, checked some specs of block-mapped (NAND) flashes from Samsung. Writes
had to be made with disk-like 528 byte blocks, but erases were 16k - I'm
happy we don't use this kind of flash, even jffs would make large amounts
of page erases when doing only small changes...

Personally I've used ext2 on flash for now - but with extreme suspicion.
How many flash erases I generate with single chmod? At least one. How many
with small change to shell script? Several I guess. And those updates are
concentrated on certain pages, probably. Thus I use flash only to store
what must be stored on flash.
