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 RIIIF did not impress us with its HDD speed. At stock speeds it was slower than the others in the grouping. However, the overclocking run shows a much higher score. In fact, it is around 4MB/s faster. Although this is not a large margin, it is significant for our purposes here. Still, this is not something you would probably notice in day to day usage.
AIDA64 does not match the scores we saw at all. They are almost the opposite. With AIDA64 we saw certain aspects of the scores drop after overclocking. While with Sandra we saw the score speed up; very interesting.
