Well, to each his own, I suppose. I’m cuuently running a 4 TB EnhanceTech RS8 SS SAS RAID system with an LSI SAS 1068E card that costs under $5,000. and does 600MB/s (RAID 5)with 8 SATA drives. Works great.
Matrox is less stringent with certifying storage options. They make recommendations, but storage specs aren’t included in the system checker that runs during system registration.
