    Are both your M.2 drives bootable when not in Raid Mode? My board has 2 M.2 drives but 1 is not bootable.
    Those are the only instructions I know to give you. Those are Asrock's instructions.

    Hi there
    I see from the Bios that there's RAID config in it - but it still needs a file system to be formatted on it.

    FORMATTED DRIVE DURING WINDOWS INSTALL

    See what GPARTED shows when booting a stand alone partition manager -- GPARTED is downloadable anywhere (and free).

    D/L GPARTED - ARRAY DOES NOT SHOW UP AT ALL

    Windows won't boot RAID unless it sees a "single Disk" in the case of RAID 0 so you will need to have this array formatted and bootable .
    AS I SAID - IT WAS FORMATTED WHEN WINDOWS WAS INSTALLED - IT SHOWS UP AS "WINDOWS 10" WHEN I TRY TO REPAIR START FROM WINDOWS INSTALLATION REPAIR SECTION

    If windows can't see the boot sectors / boot efi partition in case of efi then it won't boot.
    Test it also with a Linux Live distro - you don't have to know anything about Linux just boot and see from the file manager if the HDD's (SSD's) are seen either as 2 discrete disks or a single volume -- if you get into command mode on the Linux live distro just type lsblk -- this will show if the RAID 0 array is reachable,

    D/L 2 DIFFERENT .ISOS - ISO BURNING TOOL WOULDN'T RECOGNIZE EITHER - I USE WINDOWS 7 USB/DVD DOWNLOAD TOOL

    Issue resolved - I decided to re-install Win 10 to the RAID array - said it couldn't install because Windows MBR and drive needed to be GPT - or something to that effect.

    Using diskpart, I formatted the array and converted it to GPT - Windows installed and booting is fine. I had run into this before because I always delete the RECOVERY and EFI partitions from the drives - it is an OCD thing - don't ask -

    This is the current Disk Mgmnt situation - no way I'll leave it alone
    Benchmark below - not that impressed with it - writes much better - reads not so much.

    Other issue - the drive does not show up in Acronis when trying restore a backup - this may be the RAID deal killer for me.

    I thank you for the suggestions - how could you help when I left a card out of the deck - my bad.

    Rest and Think time before doing anymore - THANKS AGAIN!

    Your read speeds are limited by the DMI 3.0 interface to the CPU that the M.2 slots are connected to. If you put the NVME Drive in PCI-e slots with an adapter you would see your read speeds increase.

    Hi there

    How are you attempting to create the RAID array, format it with a file system and start it.

    I see from the Bios that there's RAID config in it - but it still needs a file system to be formatted on it.

    See what GPARTED shows when booting a stand alone partition manager -- GPARTED is downloadable anywhere (and free).

    Dear Jimbo,

    I am a new subscriber and I was wondering if I could ask you a question if you had a minute.

    I created a raid 0 with two m.2 nvme drives. Both are 256Gb each. I am running out of space now and I was going to upgrade the two m.2 drives.

    I have software to clone the image and reupload it using a usb key using Macrium.

    My question is can I install the image to just one m.2 drives and delete the raid on the c:?

    I have two other raids going, D: is two 4TB drives and E: is two 256GB SSD's.

    Would these be effected?

    I am a bit lost and wondering if you could help?

    I can create a new post in case other people want to do the same.

    Kind regards.
