Two USB 3.1 Type-C female connectors available. That is way below the normal performance of a USB 3.0.USB 3.1 Type-C a super fast, convenient and powerful data transfer solution. We were astonished that the USB 3.0 performance read tests give us only 41MB/s.

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. Using the on board Intel Z77 supported USB 3.0 ports This is consistent with our tests of the SSD on the docking station months ago on the older platforms using ASmedia or Etrontech controllers. We first tested it using SiSoft Sandra 2012 Physical disk test. Here are our results with the docking station attached to the ports. 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. 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 our review of the ASRock Fatal1ty Z77 Professional-M, we discovered something odd with the USB 3.0 performance.
