Western Digital Raptor WD740GD 74 GB Hard Drive
 

Designed for servers and NAS/SAN systems, the drive of choice for high-performance workstation and gaming systems, the WD Raptor hard drive is a new class of drive that matches SCSI performance and reliability while providing simplified connectivity. Make no mistake about it, the Raptor is for serious speed freaks. If you don't run a server farm or play cutting edge 3D games then this is not the drive for you. However, if you're a power nut who wants - no needs - the fastest ATA drive available then this is your baby, or dinosaur as the case may be.

My baby! Aaaaaah!

Actually I was looking at SCSI prices for a 70-80 GB Ultra-320 model and they are not that far off.

But would they provide with a noticable perfromance gain in "cutting edge" games?

SCSI is faster because has some nice tricks like tagged queueing (the predecessor of NCQ) and sync transfer. In games this is unnoticable, but when you're doing multiple disk-intensive things,
SCSI rockets away from the rest.
