matrox HD compress
What do you need this for?
I was using it in dual core system for transcoding purpose earlier and just transferred it to the new system
The start is pretty good, but to really make it "Ultimate" you may need:
1. An additional X5680
2. 9 additional sticks of RAM for 48 GB memory
3. An Areca ARC-1880iX-16 with at least 2 GB cache and BBM
4. Some additional hard disks.
Instead of using the BM tool, what does HDTach say? What tuning have you performed?

Shades of my problem early with my X7DWA-N. I got terrible results with my Areca 1680i controller. Here was an initial test with three SAS 15K.5 drives. After a long fight with Supermicro I finally got a new BIOS that corrected the problem
Here was after a BIOS change (and adding 2 more disk drives) and it still is not great but a major improvement.
