M.2 NVMe SSDs in Raid 0 array?

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.

I have booted to both - used to dual boot - Pro on one and Ent on the other

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

Thanks for the suggestions -

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!

This was the benchmark of a single Pro 960 512 GB Samsung drive
