The drives come in the VelociRaptor's signature 3.5-inch bay version with the IcePAK heatsink cooling the drive or a bare 2.5-inch form factor for server use. Don't think about stuffing one of these in a notebook, though, as they are 15mm tall rather than the standard 9.5mm. The updated drives consume no more power than the previous generation VelociRaptors and feature sustained transfer speeds of up to 145MB/s.
These specs might not hold a candle to the 200+MB/s reads and writes and much faster random-access times of solid-state drives, but in the price per gigabyte department the VelociRaptor still commands a considerable advantage. The 450 and 600GB drives have an MSRP of $299 and $329, respectively, and come with a five-year warranty.
