    The only explanation for results THAT slow that I can think of is a faulty drive. May want to RMA it.

    If it was maybe in the 200's I'd think it was the common you have SATA II and it's a SATA III drive problem that a lot of people seem to have in confusion, but this is too slow for that.

    You may find it will completely die in a few days if that's whats going on.

    Did you do a clean install of OS X or a clone? Is the firmware up to date?

    I'd try a clean install and before you install anything run the benchmark again. If the issue persists I would RMA the drive.

    Are you saying its slow because DiskSpeed Test is telling you or do you physically feel slow?

    I have to say, BlackMagic DiskSpeed is pretty inaccurate.
    My SSD gets under 30mbps R/W according to DiskSpeed Test.
    But when I run Xbench, a way better version to find out your drive speed, I get over 190w and 510r.

    Your performance looks more like connected to an USB port.
    You really connected it to SATA? Did you replace the internal HDD?
    If everything else works fine maybe really got a faulty drive.

    Faulty drive

    Sandforce controller issues or not, those speeds are too slow for an SSD drive.
