Disk Drive Controller
The system drive controller is an important part of system performance. In most modern boards your drive controller will run off of the PCI-e bus. The PCI-e bus performance can be affected by poor trace layout as well as many other design choices that show up on different boards.
For testing we use Sisoft's Sandra and Everest.
Despite being a full SATA 3.0 controller, we see SATA II performance that is slightly behind the Intel controllers. SATA 3.0 performance is right where it should be, as is USB 3.0 performance.

Everest Ultimate confirms our Sandra results and shows that while the SATA 3.0 performance is spot on, SATA II drives will suffer a little on the AMD SB850.
