Im looking at upgrading my system imminently and was wondering for HD's would 2 matching small storage (80-160gb each) drives in RAID 0 be a fast cost effective solution for putting windows/programs/games etc and a larger (500-1tb) drive as storage/junk?? If so i seen some WD800AAJS drives for £20 each. Just looking for guidance on the fastest cost effective setup. thanks
