The Raptors

Ah yes, the 150gb Western Digital Raptors. This was one of the harder choices I had to make when I selected components for this system.

They use an old SATA interface, they are small (150gb), and they are expensive.

But... They spin at 10,000 rpms and are still the fastest SATA drives you can buy. And I have always wanted some and until now have not been able to get any.
