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.

On average the XFX performs the same to a slight a fraction better than the other nForce 6-series and Intel boards tested. There's very little between the field though.
