Thanks for the correction, but that does not change the discussion.
Further, the designers of
flash disks are not stupid as you assume. The direct access occurs
to static RAM (read/write stuff).
I'm not assuming anything . Some hardware has been killed by this issue.

It seems that it's you making the assumption that all of these devices are
manufactured the same way.
The constant dirtying of the buffer will still cause excessive use of the
flash block hosting the FAT. Clearly not all devices use a load spreading
mechanism and this can lead to premature failure.
