    Hi again CountMike,

    Just for the record, I have run benchmark tests on my SSD at least a few hundred times in my test rig. I have a need to do this when testing various hardware configurations. Check out the total R/Ws and the condition of my current SSD:

    Looks like my cheap $69.00 SSD has held up pretty well while still taking a heavy pounding. Now, don't get me wrong, your recommendation is shared by many; however, I (personally) would continue testing (as deemed necessary) to try and come to some logical conclusion about why there is a difference in benchmarks here (or just leave it alone and be happy).

    @antspants: Looks like my suggestion actually had a negative performance impact. With that said, I would reverse the configuration and download the Passmark software and give that a try. And, if both of your SSDs, fit into that 4,000 test score range, close up shop and be happy!

    BTW, my SSD bechmarked somewhere in the 2100 to 2300 Passmark test score range.

    Thanks 2cents, I did download it, I opened it, I looked at it, I crapped my pants. It will take a lot of looking at. Its rather complex. Did I mention I am academically retarded? I will look at it though. Til then, I shall sleep, it's late, I'm scared the clown will wake and DESTROY me. (Not as scared as her coming across what I just wrote)

    Nice bunch of guys in here, thanks.

    No, its quite easy to run. Simply select "run all tests" from the dropdown menu above and watch er go! Now, the results you see during/after testing will be in comparison to a random selection of others and each unique test result will appear as a horizontal bar graph (with green or red bars). Once done, simply scroll down to disk score and read it (as reported by the decimal text value). Unfortunately, I can't show you that because I don't have it installed right now. Again, it is easy!

    The 4372.1 is your overall benckmark score as compared to mine which is/was a measly 1500.

    Your individual disk mark score of 14013 appears to be bogus/overstated. That means, Passmark did not find/fix/correct all the issues found in previous versions relative to Samsung SSD 840 benchmark testing:

    My last suggestion is to download ATTO and run that on both SSDs to see if they compare favorably using that utility:

    ATTO Disk Benchmark Free Download

    Here are my benchmarks using the above utility. You can run it for each SSD by selection from the drop-down menu:

    This is my last suggestion. Your choice to try it or not. I wish I had problems like yours (I should be so lucky)!


    Cheers mate,

    As suggested

    OS Drive - Something isnt write <- See what I did there?

    Just for good measure, this is a Kingston HyperX 3K 120Gb SSD Rev 3

    I think I might send these to Samsung Support, which they seem to have very little of

    Hmm... Your OS drive R/W speeds still do not look realistic. Moreover, these new benckmarks (at varying speeds) make it look worse than your non-OS drive. BTW, the other two benck marks look good IMHO. Now, what to do?

    At this point, I'm not sure where to go but I would start by checking my BIOS to make sure your OS drive SATA port is set at AHCI (not IDE) but I doubt that is your issue. Next, I have to ask, are there options available to set when you run the Magician software? If so, are they changeable after installation? Would it be possible to do an option stare and compare between the two drives?

    EDIT: It doesn't look worse but it just doesn't look realistic (unless you have a super drive).

    So, I did a bit more reading, and I did find out the Magician does have some options that are specific to "only" the OS drive and that Rapid DRAM may be one of them. I'm starting to believe that option is set and the benchmarks might indicate you are actually writing to the DRAM buffer (that would account for the super write speeds maybe), and then the DRAM buffer continues the final write process to the SSD. Now, if I am correct in my theory, this could be good news and bad news combined. The good news is that your SSD would give the illusion that it is running at super speed but the bad news might be that the SSD writes might continue for a longer period even after the data transfer has been reported as successful. Please understand I have no understanding of this new Samsung design and I am only guessing at this point. However, if it were my SSD, I would prefer to see the true R/W benchmark speeds (as apposed to a simulated benchmark). BTW, did you notice any RAM reserved for that function because Samsung says it could grab up to 1GB of RAM to use with that feature.

    Ill have to look into that. Right now, I am doing backflips trying to register the drives with samsung. They aren't making it easy, it involves pulling my drives out of my case and contorting my body, swearing a lot and generally foaming at the mouth.

    Ill have a look at the settings you mention..
    Thanks my2cents, if nothing else you've helped me get educated. For that I am grateful
