If I'm buying a new computer, does it make much difference in normal usage if I get a 7,200 as opposed to 5,400 drive? Currently the only people selling 7,2 IDE drives are Seagate, a friend has had bad experience with them so I'd rather stick with Quantum. Quantum only makes 7,2's for SCSI, which will probably work out a bit too expsneive for how much more performance I will get. Comments?
