As much as that is a pretty quick drive, im not really sure on how reliable the current generation samsung drives are, their older drives werent the most reliable drives out there, not sure if things have changed however but for $84.99 thats probably a pretty good deal.VelociRaptors are great drives, I have one, but they're over priced, and not the fastest.
The Samsung drive on top is a 1TB 7200rpm drive that Newegg lists for $84.99.
(out of stock right now though)
