SATA, USB and FireWire Speeds
Using HDTach 18.104.22.168 and a few handy peripherals, we were able to get some benchmark numbers off of both the SATA controllers on the boards as well as the USB and FireWire connections.
SATA Performance — South Bridge
Here we tested the two south bridge based SATA controllers. We used a new Raptor 150 GB 10k RPM hard drive for the test drive.
Taking a 7200 RPM IDE external hard drive from Western Digital we use HDTach to find the top transfer speeds on both motherboards.
This external drive has both USB 2.0 and FireWire support so these results are from the same drive with the FireWire connection.
The storage performance on the SATA connections of the nForce 590 SLI chipset is very good as shown in our HDTach results. The USB and FireWire results are a bit lower than the other top boards we have tested here and I was honestly expecting a bit more from this particular motherboard. But in all, the results are pretty good and you’d be hard pressed to notice these performance differences in your actual usage patterns.
