Performance is pretty good and memory latency is low as well. It still doesn't exceed the Asus Commando however, even though it's also running at 3-3-3-9.
Disk Performance:
The SATA read tests were conducted with a 74GB Western Digital Raptor using HD Tach 3.0.1.0's 8MB zone test. The USB 2.0 tests were done using an ATA133 160GB Maxtor DiamondMax 10 hard drive (model number: 6L160PO) using the same 8MB zone test enclosed in an Icy Box USB 2.0 hard drive caddy. We recorded the average read speeds in all cases.

Across the board, peripheral and disk performance is excellent as overall it keeps up with the other P35/P965 motherboards across the board.
