So I upgraded my cMP 3,1 with a Velocity Duo x2 card with two Samsung 840 Pro 256GB drives. I pulled these drives from my Windows PC, and I know they work fine. The Duo is plugged into the top PCI Slot (marked x4). It's getting a R/W speed of 190MB/sec with Disk Speed Test which is horrible performance from a SSD. Infact, I did the same speed test on my AppleRAID mirrored 4TB drives and got about the same speed. I also tried in the 3rd slot (x16) above the video card, and the cMP wouldn't even see the card. I'm at a total loss here.. At first I tried it as a soft AppleRAID (stripped), same speed.. then I tried using it's on-board Marvel BIOS making a hardware stripped RAID. Again, same speed. Any suggestions?
