What kind of HDD are you using for your OS?

My two raptors in raid-0 are sold, so im looking for something good for my OS that will be almost as fast.
Im just curious what you folks are using.

Well I have an 80gig WD in 3 computers as the boot drive, but I still have 36gig raptors in raid-0 in my main rig.

Nothing outside SCSI is "almost" as fast as a Raptor.

I have a hodgepodge of 120 to 200GB IDE drives ....
OS is on a 200Gb drive .... nothing super fast, but it's fast enough.
