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.
The P7P55 WS has excellent HDD performance; it comes in at the top of the group for the P55 range. This is good news for AV editors and other content creators.
Everest backs up our HDD findings from Sandra. This is one fast board for SATA II HDD performance.
