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.
Ah, we do see an issue here with HDD performance. However, it is not great enough to account for the very poor HyperPi showing. Still, I would have thought to see better HDD performance from an X58 board.
Stock HDD Performance
Overclocked HDD Performance
Stock USB 3.0 Performance
Overclocked USB 3.0 Performance
Here is the reason we include both Sandra and Everest. As you can see, our Sandra scores show the X58A lagging behind the ASUS X58. That is not the case with Everest; instead we see performance where it should be for the drives we are using. So, now the mystery surrounding the poor HyperPi showing deepens even further.
