Man, I remember lusting over getting a WD Raptor back in the day. They were so much more expensive and lower data density it I couldn't justify for my low budget.

As was already said, 160 was pretty common, think increments of 20 or 40 is what i remember. Raptor drives had kinda odd size increments compared to other consumer drives. Looks like it would be 36Gb circa 2003.

I once got some retired scsi drives. Man 10,000rpm drives were loud and hot...

Thanks for bringing back some old memories
