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.
HDD performance was not as good as it could have been. Granted, you are still running at 200MB/s read speeds, but even this falls behind the 240+ we have seen on other motherboards. The SATA 3.0 and USB 3.0 speeds are right where they should be.
Everest again backs up our Sandra numbers and shows us that our issue seems to be linear read at the end of the drive. This is an unexpected item and could be due to the Trim firmware on the Force 120 more so than the SB850 controller.
