    Can anyone explain these benchmark results?

    This is what the latest version of Samsung Magician shows for my system. I was expecting to see the NVME drive far outperform the SATA drive, but that was not the case. The NVME drive is my boot drive, and the SATA drive is for temp files, My Documents, and general work-in-progress stuff. Based on these results I'm thinking maybe I should swap the usage and use the SATA drive to boot from.

    One possibility is that the SATA drive is set to use Rapid Mode, which essentially buffers the data I/O to the drive, so maybe this is the reason for the results I got. Perhaps Samsung has gimicked their benchmark to take advantage of that.

    Have you installed the Samsung NVMe driver?

    Yes, but....

    I thought maybe the driver had been updated, so I downloaded and reinstalled it.

    No change in the benchmark results.

    Device Manager says the driver is Microsoft Ver. 10.0.18362.1, and the driver details looks like this:

    Naturally none of this matches the Samsung driver version number of 3.2, so it's not clear what driver is actually running. The Driver Update function says the most current driver is installed.

    Thanks for that - I hadn't thought about looking at Storage Controllers.

    So I did, and it shows the same as that message thread - I have the Samsung 3.2.0.1910 driver installed.

    Check with CrystalDiskMark. The SATA 3 theoretical limit is 6 Gb/s, which is equivalent to 750 MB/s.

    Agreed. You need a "second opinion". Try CrystalDisk.

    You have all current drivers and Magician does read 970EVO's, so I can't explain why the scores are so low.
    One idea is there might be a BIOS setting to set the NVMe at SATA speed? Wouldn't hurt to look.

    Here are the Crystal results:

    Top one is the NVME drive, bottom SATA.
    The data doesn't precisely match up, but it does clearly show that the SATA drive is out performing the NVME one by a fairly large margin. Obviously something somewhere is wacked.

    I'll look at the BIOS and see if I can find anything interesting. My motherboard is Asus P8Z77-M and I do believe I've got the current BIOS. I'll check that too.

    The only thing I could find in the BIOS that looked like it was applicable was this, and it is enabled:

    It is AMI Native NVME Driver Support

    Simple answer, you have Rapid Mode enabled for the SATA drive. You are getting "ram disk caching" speed results.
    Turn off Rapid Mode for the 840 PRO and you will see the true performance of the SATA drive.
