We use WD Velociraptor which are 2.5" 10 krpm SATA disks. They're
mounted in a heatsink that makes the fit into the same mount as a 3.5"
disk. Good preformance. Decent prices and capacity. The failure rate
has been low.

One of the issued with the fastest drives is that in order to achieve
the highest spin rates they often have smaller platters and so lower
capacity. Cost/GB goes up.
