How do you use the SATA 6.0Gb/s ports

I recently bought a ASUS P6X58D-E Motherboard and I tired to use 1 of the 2 SATA 6.0Gb/s ports with a Western Digital Caviar Black 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive, but I can't get the motherboard to recognize the Hard drive. It works fine in the other 6 SATA ports. How can I get my hard drive to work in the SATA 6.0Gb/s port?

  1. If it works on the sata 3gb/s i would use that. I doubt you will notice any speed improvement using the 6gb/s even if you can get it working. 7200rpm hdds read/write speeds are lower than 3gb/s. From what i've read even most non-raid ssd's are slower than 3gb/s.

    Analogy:
    A go-cart will be just as fast on a highway as it will be on a go-cart track.

    The 6gb/s sata are currently more for future proofing for upgrades than for currently available hardware.

    I know I can connect to the 3gb/s ports but I am running out of ports on my motherboard and want to use the 6gb/s ports too. Are the 6gb/s ports not backwards compatible?

    Yes the 6gb ports are backwards compatible.

    I have heard that the WD black 6GB drives need a firmware upgrade to work on the Marvell ports. See if you can find a firmware update for your drive.

    Search the ASUS forum for WD black and you will find a post about this issue.
  4. We have 2 x WD1002FAEX cabled to the ASUS PCIE GEN2 SATA6G expansion card:

    And, we configured an XP software RAID 0, for speed
    chiefly because that expansion card is not a RAID controller.

    So far, so good.


    p.s. SATA/6G ports are useful for 6G rotating drives that
    also have a large cache: when they are combined
    in a RAID 0, their hardware caches are additive:
    thus, 2 x WD1002FAEX ~= 128 MB of HDD hardware cache.

    Here's a test we did with a small file chosen to fit
    entirely within the combined HDD hardware caches
    so we would be measuring only "buffer-to-host":
