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.




Comparing the MSI Eclipse SLI's standard JMicron chipsets to Asus' more professional SAS is a little unfair, however the Asus does cost less than the MSI despite this. The ICH10R performance was consistently slightly lower, but the JMB363+322 port multiplier that converts a single PCI-Express x1 lane into two SATA into a further four SATA (read: bottleneck) and it's evidently shown in the 30MB/s performance gap.

The JMB362 used for eSATA (and IDE), which we've accused of being poor since Vista launched, shows abysmal performance at more than 40MB/s slower than the Asus P6T and barely faster than the fastest hard drives out today.

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.


On the other hand, at least the USB 2.0 performance is consistent and excellent.
