Nope: SSDs are made of *RAM*.  If you want them to retain anything at all
they have to be battery backed.  And being made of RAM, they aren't subject
to wear-leveling or anything; they don't wear any more than main memory 
does.

In fact, unless you need a whole lot of ephemeral storage on a system
where it's impractical to install it as main memory and make a ramdisk
out of it, they have little justification -- especially at their price,
which is uniformly pretty high.
