Ignoring the TRIM issue for a moment . . .
You're probably best off saving SSD storage for cases where you have lots
of reads and little to no write activity, unless you enjoy buying new
SSDs a lot. Actually, let's not ignore TRIM; the work-around for lack of
TRIM support on some drives is a "garbage collection" routine that
exacerbates the problem of having to replace your SSDs more often if you
do a lot of writes.
I guess I would only use SSDs on servers in the same cases where I would
let myself be talked into using MySQL -- cases where you just treat it
pretty much like a read-only data store, and do not have to (safely) add
or change data stored there most of the time.
