Hmmm.... I think that actually really slows down your computer. More places for it to have to look for something. Less drives the better. I have a C: drive with has all my system stuff, and it is one single 500GB drive, and I have another 500GB drive, which is all my documents, the reason for that is if the computer crashes, all of my important documents (Music, Videos, other stuff) is always backed up, and can never be effected.
