Ok, I have 4 identical Western digital 160GB 7200rpm 16mb cache SATA hard drives. I need 2 of those hard drives to run in RAID 0 Then I also want the other two other drives to run in RAID 0, but I also want them to mirror the other RAID 0 setup like a RAID 1 setup. See where I'm getting? Heres a diagram http://img169.imageshack.us/my.php?image=raiddiagramzp8.jpg Is this possible? How would I do this task? Any help appreciated.
