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.
Now we have the final piece of the CPU to Memory to HDD puzzle. Although the scores here are not that far off from the rest of the group, they are off enough that we can draw a conclusion that there is a slight performance loss pulling information from the HDD and getting it into memory, then to the CPU. The good news here is that with the small hit you are taking it can probably be corrected with a few tweaks to the BIOS.

Everest tells us a similar tale, although the buffered read during our overclocking test kept showing up with results that were very far off what we should have been getting.
