I think this might in practice be a red-herring.

If you could convince the system to set aside an amount
of RAM for dirty disk buffers and to write them all when
its filled or on application demand (and in a way that
preseves integrity like soft updates) so that for any
given flush each sector is written at most once, then
you can run for years for most CF cards and most practical
usage patterns that don't really demand a hard disk.

Assume you have cron drive a flush once an hour and
consider how long until a sector dies, even if the drive
itself does no wear levelling at all (and I believe some
do it internally).
