    Samsung SSD 840 Pro performance seems to have declined over time.
    Operating System - Windows 10.
    SATA II

    When I compare nearly one year old performance score and now, there is a difference in Seq Read and Write speed change which has gone up significantly, even well over SATA II range and CrystalDiskMark score is over SATA III speed. The laptop I am using is SATA II. The 4k-64Thrd and Acc.time has gone down significantly. Magician test doesn't seem normal too.
    A year ago
    WEI - 7.8

    Now
    WEI - 7.7

    What is the problem, will performance be affected significantly? What is the solution?

    Is RAPID Mode enabled?

    This can improved the performance under certain conditions because it is caching data in RAM. There are some comparative results here.

    If RAPID mode is not enabled then what you are seeing is similar to the subject of this thread (which is unresolved).

    Thank you! RAPID mode was enabled and when I disabled it, the benchmark improved significantly. And it seems normal now. However, the actual file copying/pasting speed hasn't improved.

    Will I miss out anything after disabling it? I didn't see any improvement at all when it was on. From what I read, it uses RAM and processor to speed up performance but I think that might negatively affect overall PC performance for old processors like Intel Core 2 duo 2.0 Ghz and 4 GB RAM.

    I would leave RAPID mode disabled if you have only 4GB RAM. I would expect it might cause increased use of the page file which would be counter-productive.

    Great! I will keep it disabled.
