Hey, im a little bit confused so any help will be greatly appreciated! I have a ds3 (rev3.3) and installing x2 HD's onto it. The first is a WD Raptor HD (md1500ahfdrtL) which will be used for o/s and applications. The other is a WD 320gig SATA2 drive (3200ksrtL) ill be using for media. Now question is can i install these into just the regular Sata connectors, or do i have to use that sata card my mobo comes with? And will i also be able to install windowsXPsp2 onto the raptor w/ out any problems or are there some form of compatibility issue that lurks around?
