    AHCI is the right mode for PCIe NVMe SSDs.

    1. the performance is better (i've tested it) (use google translator)
    2. only in AHCI you can install and use the manufacturers driver and tools

    The RAID on mode is the default setting of the wonderful Dell BIOS.
    RAID on mode operates over the SATA Controller, AHCI directly over the PCIe Interface.

    I'm not sure. I use Raid with Intel RST. On various websites I read that ACHI is better for SATA SSDs, but for M.2 PCIe SSDs it is better to use RAID (even better when you have multiple SSDs). Raid uses MVMe controller for PCIe SSD and Sata controller when disk is Sata SSD.

    Your device, your decision. You can take my advice or test it yourself.
    Let me know if you have successfully installed the Samsung NVMe driver in raid on mode.

    !!!! @Sk0b0ld, @QuillP :) !!!

    My apologies, here is a correction to my previous post, which I edited too.

    Use AHCI (not as in my original post where I suggested RAID), then install Samsung driver (especially if primary with system).

    I answer you because I have pretty much the same SSD config. :)
