I also just set up to western digital 120 GB 8MB cache hard drives in a raid 0 array. I used Nero to test the drive speeds and it reported them reading/writing at 55 Mbps which is pretty fast compared to the serial ATA drives that are out right now. The 55 Mbps was a high score on average they are probably more at 50 Mbps. Just use Nero get it from Kazaa. Peace Elpierco
