slackworth, ask them about a 15k and 20krpm raptor and say you saw this article. I'd love a 20krpm raptor! If they can get 4ms access times and 140mb/sec avg it would be the king of kings, currently the velociraptor will be killed my 2 * samsung 640gb drives in raid0 except for seek times of course but a 20krpm drive would be about the same speed hopefully as 2 raided non-raptor drives. It may actually be worth a £190+ price tag for a change.
