Ok, that's why I said "most". And if your El Cheapo hardware has built
in wear leveling, then doing wear leveling on top of that is always
questionable. It might not make things worse, but it's probably not
very efficient.

Now if you have El Super Cheapo hardware that explicitly states you need
to do wear leveling, that's a different story ;).

At least to the non-geeks. I can remember buying spare hard drives and
carrying those from machine to machine if I needed to do big transfers
;).
