ASMedia USB 3.0 vs Intel Z77 USB 3.0 performance on ASRock Fatal1ty Z77 Professional-M

In our review of the ASRock Fatal1ty Z77 Professional-M, we discovered something odd with the USB 3.0 performance. In our tests, we have used the latest BIOS and Intel USB 3.0 and ASmedia USB 3.0 driver on the same board to test it’s performance. In the results below, we also tested the same SSD, a Kingston SNB 425 Vseries SSD using the external Sunbeamtech USB 3.0 docking station.

Here are our results with the docking station attached to the ports. We first tested it using SiSoft Sandra 2012 Physical disk test.

Using the ASmedia USB 3.0 support ports

We get a read performance of 202.15MB/s. This is consistent with our tests of the SSD on the docking station months ago on the older platforms using ASmedia or Etrontech controllers.

Using the on board Intel Z77 supported USB 3.0 ports

To ensure everything is working correctly, we checked the device manager and also ensure that the latest driver (available from the ASRock support website) is installed.

We were astonished that the USB 3.0 performance read tests give us only 41MB/s. That is way below the normal performance of a USB 3.0.
