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.
HDD performance presents us with some interesting numbers. When we overclocked the CPU the performance actually went down a little.
Stock HDD Performance
Overclocked HDD Performance
Stock USB 3.0 Performance
Overclocked USB 3.0 Performance
Everest shows us a similar story to our Sandra numbers. For some reason things slow down when we overclock the CPU.
