Hi there, I have a Mac Pro 2008 running Snow Leopard, with 4 WD RE4-GP (WD2002FYPS) SATA 3Gbps hard drives. I recently bought a Sans Digital TowerRaid TR8X enclosure for SAS/SATA drives with two SFF-8088 connectors, plus a RocketRaid 4322 SAS/SATA RAID card, to move these disks to the external enclosure, expand capacity by buying more disks, and mount them on RAID 6. I had to return the RR 4322 card because I suffered constant freezes when transferring files to the RAID volume. I know that the disks are SATA (no SAS) and that might be the source of issues, but I thinked that a SAS/SATA RAID card like the 4322 would work well with them. Or maybe it was just the same issues others seemed to have with this card and Snow Leopard. In any case, I still have to buy a SATA or SAS/SATA RAID card to connect to my enclosure through the miniSAS interface, Snow Leopard compatible, and preferably that works well with the SATA drives I already have. Any recommendations? nanofrog? I'm ok with a SATA RAID card, but because the enclosure supports also SAS drives, it would be better if the card supports both SAS and SATA drives... just in case I decide to go with the SAS drives in the future. Thanks in advance.
