Memory performance isn't hugely wonderful, although it is certainly adequate for Core 2 CPUs. Despite the fact we were running 3-3-3-9-15-2T timings, the performance is still short of the MSI nForce 650i SLI board (MSI P6N Platinum) we tested previously. It's also a fair bit slower than the similarly priced Gigabyte GA-P35-DS3R which uses Intel's new P35 chipset, even when it's running an E6300.
We were unable to run 1T stable, unlike the other 6-series boards we've tested, this can be attributed to some of the loss in memory bandwidth.
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.

SATA and USB performance is very good equalling the other boards tested. No Firewire or eSATA on this mainstream board means we're devoid of these results.
