  1. Your motherboard does not have native SATA 3 (6Gb/s) ports.
    Your motherboard uses a Marvell 9128 controller for the 6Gb/s ports which has a data bandwidth of PCIe x1 at 5Gb/s (500MB/s).
    You won't get advertised Read/Write speeds from any current generation SSD you connect to those ports.

    That being said, your ATTO benchmark results still should be higher.

    Double-check that your drive is connected to port SATA_6G_1 or SATA_6G_2.
    See page 2-2 of your motherboard manual for the location of the ports.

    Dereck47, thanks for your reply. That's what I thought as well, that it still should be be higher than what I am getting. I've read about the native vs non native SATA 3 but the numbers suggest something else is going wrong. I guess I will have to settle with this for now.

    Update the Marvell drivers and see if that helps any. http://www.station-drivers.com/index.php/10-drivers/47-marvell
    Download and install version 1.2.0.1039 dated 02/10/2013.

    If you are fairly confident & knowledgeable with regards to firmware upgrades then you can also upgrade the Marvell firmware to version 2.2.0.1125b dated 06/06/2012.
