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 on the P6X58D-E is good, but then again, the Intel IHC10R is a good SATA II controller. The rest of the performance is good, but we did find it odd that the HDD performance dropped when we overclocked the system.
