SATA and USB Speeds
Using HDTach 220.127.116.11 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 Maxtor 300 GB 7200 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.
SATA performance is equal across the board and on the USB test we see the performance is almost equal as well.
