Pros: Quiet, fast, low power. Basically better in every spec than the two-platter, 9mm, 500GB Scorpio Blue. Low profile is probably a plus, but didn't matter for my Mac.

Cons: Clunk, clunk, clunk. The spindown time defaults to around 1 second. OS X does not reset it when you tell it not to spin down the drives when idle. Search "hdapm" for the fix. Linux has this built in (hdparm?).
