Just wondering what other machines are like for hard drive performance. I have two machines, one running a Seagate 320 GB 7200 RPM drive, the other with a Seagate 500, 7200 RPM drive. The performance index shows them as 2.9 and 3.0, respectively. In Vista, they were both 5.7 and 5.9, respectively. I'm wondering if this is related to chipset driver optimization...something else...any thoughts?
