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 AIDA64.
Drive performance on the UD4 is actually pretty good. It falls right in between the P8P67 Deluxe and the P8P67 WS from ASUS. The performance between these three boards is only one MB/s each.
