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.
Here we find the HDD performance to be behind the Revolution. It makes the faster HyperPi scores a little puzzling, but not too much. With speeds like this we can still expect decent performance in rendering and also transcoding.

Interesting again; we see pretty good performance from the HDDs with AIDA64. Although there is a slight reduction in the linear read speed, it is not that large of a gap. Still, it is good to know that you can expect this level of performance and when Intel replaces the Cougar Point you can expect to get at least this level of performance, if not more.
