My local CompUSA has a great deal on 30G HD. I was thinking about purchasing 4 and setting them up on raid 0. But when you set up 2 HDD on raid your supposed to use a seperate channel for each drive because of the disability of more than one instruction to be sent thru the IDE cable at once. If this is the case, wouldn't setting up 2 HDD on each cable have no advantage? How about using the new Serial cables on the new motherboards? Any difference?
