SATA and eSATA Performance

Website: HD Tach 3.0


SATA performance sees a fractional improvement to a solid 82MB/s regardless of IGP use taking up some subsystem resources. In comparison the SB700 and SB600 are fractionally slower, and the IGP has a slight effect. Either way, this is exactly what we'd expect to see from SATA - it matches other chipsets.

USB 2.0 Performance

There are no words other than "epic fail" to describe AMD's USB 2.0 performance. We thought it was an error at first - that we were missing something, but after double checking the drivers, having no issue what-so-ever with connectivity on USB and talking to AMD, this is simply the actual performance.

So much for claiming things got better with SB700 - if anything, they've got worse and SB600 wasn't exactly great to start with!

A good MCP/ICH chipset like those from Nvidia or Intel will max out the USB 2.0 potential at 34.6MB/s exactly, when we connect up a hard drive to it and flood the bus. Those from AMD simply whither.
