SanDisk's new, fast drives
 

This solid state disk drive appears to leave the WD Raptor in the dust. I hope it will soon be available in a "drop in SATA" format.

$600 for this :

"In addition to being reliable, these drives are fast. SanDisk claims a sustained read rate of 62 megabytes per second and a random read rate of 7,000 inputs/outputs per second. In plain English, that means it’s more than 100 times faster than most current hard disk drives."
