SATA and eSATA Performance

Website: HD Tach 3.0
We tested the SATA and eSATA performance with an Intel X25-M SSD to maximise the use of the SATA connections to show up any core differences in raw performance.

SATA performance of the ICH10R chipset is generally comparative between both the boards - there's only a couple of MB/s between them, but the performance of the additional JMicron chipset is simply appalling. This chipset provides not only the seventh internal SATA port but also the eSATA as well. The Gigabyte board might not have a specific eSATA port, but it comes with an adapter in the box to adapt internal ports instead.

USB 2.0 Performance

We tested the USB performance with an Intel X25-M SSD and a SATA to USB adapter to saturate the USB bus in order to look for any performance drops.

USB performance is excellent and exactly equal between both boards.
