heapest I have done it: 8 total (2 arrays) of 4x 1TB Western Digital Caviar Blacks in RAID 10 (mirrored-striped, desktop-class drives do not like RAID 5, 6, etc, since the on/off TLER option was removed from user changes but mirrored plays nice) installed in two PowerEdge T310 servers.Configured GPO as above (redirect files and folders except music and video).
