HD Tach
We used HD Tach 3.01's 8MB zone test to measure basic SATA throughput and latency.

Sustained read speeds are similar across all three contenders, but the Intel chipsets have a slight advantage over the nForce in the burst and write speed tests.

The Nvidia chipset attains quicker access times, though.

CPU utilization results are within HD Tach's +/- 2% margin of error in this test.
