I wanted to see how the sata of another 785G mobo compared to my current one but got some weird results. My 30GB Vertex was getting 1/3 the normal write speeds and about half the read speeds. I'm wondering if having a 2.7Ghz single core Sempron for the cpu would have this kind of effect. When I first tested the drive, it was using a 3.4Ghz Phenom X3 720 cpu and I'm wondering if this might have made a difference. I can't believe a Gigabyte mobo could be that bad. All factors such as drivers were identical too.
