Hey, well I missed the 80 gb WD deal. Tommorow they will have the 120 gb Hard Drive for 50 bucks AR. Right now I have the 80 gb version. I was planning on getting another 80 and doing a RAID array. Can I still do this even though the drives are different sizes? I know nothing about RAID but one general question I have is what is the advantage of RAID vrs. just plug in the hard drive to the mobo(is this a completely pointless question?)? Can you reccomend me a cheap but good RAID card?
