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.

On page 2, we used CrystalDiskMark to verify our results :

  1. Aw, this was a really nice post. In thought I would like to put in writing like this moreover – taking time and actual effort to make an excellent article… however what can I say… I procrastinate alot and under no circumstances appear to get one thing done.

  2. Vamos a poner como ejemplo el caso de superar el miedo a la penetración vaginal, porque la anal será parecida.
