    Only give me a WEI Rating of 5.5?

    It is SATA 6.0 on a SATA 6.0 port.

    The Magician tests show it more the maxing the read write times.

    I set for RELIABILITY. I set it for PERFORMANCE. I set it in RAPID MODE too... 5.5 every time. Everything else is in the mid - high sevens. Whoda thought the SSD would be the bottleneck?

    What gives?

    You may want to download BrainSplatter's FileBench utility to see if you have the slow read on old files issue.

    See:
    Samsung 840 EVO read speed drops on old-written data in the drive - Page 93


    I would also run Techie007's SSDReadSpeedTester utility too.

    See:
    Read speeds dropping dramatically on older files; benchmarks needed to confirm affected SSDs


    If you are not registered on that forum, you will not be able to download these files. Worth registering just to have access to these tools.


    When you have downloaded the above, reboot your system, let it sit idle for 10 or 15 minutes and then run one of the tools you downloaded.

    While both take a screen capture automatically, I would also use the snipping tool to capture the graph in FileBench too. Make sure to resize the program windows (after it has finished running) so only the graph is fully visible (and the specific file names are not showing).


    I am guessing that running MyDefrag, or better yet DiskFresh will restore the performance of the drive to almost like-new condition.


    See:
    Download and install


    Download, install and run the above program with the Monthly Data option and make sure before you do to take before and after of the two read utilities above.


    See:
    DiskFresh - Refresh Hard Disk Signal


    Download and install program and run with the Physical drive selected to fully refresh the whole drive's capacity (even some of the partitions we can't normally touch).


    Again, a before and after of FileBench and SSDReadSpeedTester, all testing done after a reboot and some idle time, will really show if this affects your system.



    I highly recommend to not use RAPID - it is actually detrimental to real world performance as these utilities can show.

    James D,

    Not when it was installed, but Idk if I had the mechanical in before I ran the WEI. I will pull the second and rerun the score.

    I don't know, but I tested the OCZ Vertex4 before and the rating was 7.9. Unlike the HDD that was capped at 5.9, SSDs are not all the same.

    With the 840 Pro I get this:
