Ok here is my situation. I am planning on purchasing another harddrive as I am filling up quickly. A friend was telling me about raid setups and I also wanted to mess around with that. I want to do a setup where it access files from both drives, RAID0 I believe. I currently have WD 10k 40gb drive that I use mainly for programs and win xp. WD 40gb for Vista, messing around Seagate 200gb for music, DVDs, pron I was thinking of getting another 10k drive setup in RAID0, but I wasn't sure if I would notice that much of a difference. Any suggestions? I also thought of getting another 200gb and leave teh 10k drive as is.
