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 used Sisoft's Sandra.
The controllers on the three platforms use the same ICH built into the P55 chipset. Since we didn't have any SATA 6Gb/s HDDs to test with, we couldn't test the SATA-III performance.
