Serial ATA performance — continued

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

The GeForce 9300 doesn't really distinguish itself in HD Tach's burst and sustained read speed tests, but it races out to a healthy lead in the sustained write speed test.

HD Tach's margin of error in the CPU utilization test is +/- 2%, and that still gives the GeForce 9300 a healthy advantage over the G45 Express.
