Just so you know, in Jan '09 there was a thread on the linux raid list
where they discussed the TRIM command on SSD's. The gist of the
conversation (as I understood it) was that for SATA based SSD's, the
results of a raw read afterward were non-deterministic, ie you
couldn't be certain what you'd get back.
