SATA and USB Speeds
Using HDTach 3.0.1.0 and a few handy peripherals, we were able to get some benchmark numbers off of the SATA controllers on the boards as well as the USB connections
SATA Performance — South Bridge
Here we tested the south bridge based SATA controller. We used a Raptor 74 GB 10k RPM hard drive for the test drive.
USB Performance
Taking a 7200 RPM IDE external hard drive from Western Digital we use HDTach to find the top transfer speeds on both motherboards.
The numbers are very close here. With the closely related southbridges on the abit boards this also falls within the expected results.
