The original 10,000RPM Raptors have an excellent track record, though they are understandably pretty pricey (~$10/gig as opposed to ~$2/gig in other drives). Western Digital has upgraded them, doubling the cache to 16MB and the max transfer rate to 3GB/second. They also upgraded the looks, and it has a bit of a Mordor theme now. Black spikes and all that — great heatsinks I’m sure, but it looks kind of evil.
