But, since they're cheap, it might be interesting if someone tried that and let us know how it goes...

(and I should mention we have the same problem with using them as FreeDOS boot (and thus C:).  We write some data there, but nothing like using it for swap ;-)

For boot I would think they would work for darn near forever since they
will be getting little in the way of writes.  For / on the other hand,
especially if you put some home and tmp directories on them, there are
enough writes to kill them quickly.
