I've always figured that if something was already in the drive cache, it
would probably transfer at (close to) 3Gb/s, but I don't think the actual
drive itself could read data anywhere near that fast.
Somewhere I saw a RAID array of (I think) 24 SDD's. While I don't recall
what the transfer rate was, it was insanely fast. Maybe someone here posted
it. Don't recall.
