Disk Drive Controller and USB 3.0
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.
With the inclusion of SATA 3.0 on newer motherboards, we have added that to our normal testing suite. As there are multiple methods for including this on the motherboard, we may see large differences in performance. USB 3.0 performance on the ASUS P7P55D-E Pro is also quite impressive getting us speeds close to some attached SATA II drives.

Again we see from Everest that our impressions of the HDD and USB 3.0 performance are accurate. The ASUS P7P55D-E Pro does well here.
