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.
Now we see the reason for the poor HyperPi numbers. The HDD controller on the ION is not as fast as the one on the ZOTAC Pineview D based board. With an almost 20MB/s difference in HDD performance and slightly lower memory performance, the ION drops behind. Now, although this is disappointing, it is unlikely that you would need the type of computational power used in HyperPi with the AT3IONT-I Deluxe.
Stock HDD Performance
Overclocked HDD Performance
Everest shows us some additional information about how the HDD performs on the AT3IONT-I. We see that while the read numbers are generally not too bad (Random read is actually pretty good), the linear read score is very low.
