I have a brand-new rig that sports two WD Raptors in a mirrored array. I wanted the speed of the Raptors and the convenience of a mirrored array. But I wonder if a mirrored or striped array (1+0, 0+1, or some other RAID number) using four 7,200rpm drives would be faster than the above array. And how would the price compare?
