i have a 74GB raptor for win7, another for games. everything else is storage. have a few 500GB, 1x750GB, 1x1TB and now 1x1.5TB drive for storage. had to throw out some old 30 and 80 gig drives a while back.
hoping to get an intel SSD in the coming months for the OS - but not till the trim question is answered (and they drop in price a bit). an 80GB one is enough
