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.
For HDD performance the GA-890FX makes a little bit of a comeback. It is up there with the best of the P55 boards.

Everest shows us slightly higher performance numbers than what we saw with Sandra. But they are within about 2%, so there is nothing out of the ordinary here.
