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 AIDA64.
HDD performance was also very good with even the SATA II performance coming in slightly higher than the competition at this point.
AIDA64 backs up our findings with Sandra.
