I'm debating on whether to get a WD 160JD RAID 0 array or a 74GB Raptor for general Windows use. I do eat a lot of storage space with CD images, music, and large game installs (UT2k4!!), so the space is a concern. Would the 160JD RAID 0 array be nearly as fast running through the ICH5R on my IS7 as the single 74GB Raptor?
