i do.....2 7200 rpm 76gig running in RAID 0 config, and if you want to load things like music and movies, thats where you'll see the biggest difference. RAID 0 i don't really understand, but from what i can tell, your machine can pull data and save data much faster because you're pulling data from 2 hard drives at once. the only real problem is if one drive fails, you lose the data, but you can run in "mirror" and if one dies, you have a good one with a copy of everything.....look it up on the net, not here, and you'll probably find alot more info
