help needed for configuring Prime H370 Plus for NVMe RAID

[tgw]

I need help for configuring my system please, I have been running in circles.

 

Situation:
I have a ASUS PRIME H370 Plus motherboard (i7-8700k) with a connected SATA SSD and Windows 10 Pro installed.
Settings in BIOS are:
- PCH Storage setting SATA controller enabled
- PCH Storage setting SATA mode AHCI
- SATA SSD on SATA port #3
Boots with CSM disabled, Intel RST was running in Windows.

 

What I want to do:
- install 2x NVMe SSD Samsung mzvlq512hblu-000h1 (they are blank, unformatted)
- mount as RAID 1
- transfer (clone) Windows 10 onto RAID volume
- set RAID volume as boot disk

 

Trying to do that, I have been running into trouble:
- after I installed the 2 NVMe on the motherboard, the computer booted, but RST stopped working. I reinstalled RST with the latest version, but then it refuses to start, claiming "unsupported platform".
- at that point, I could see both NVMe in BIOS listed under "NVMe device configuration"
- I activated Intel RAID optane in PCH storage settings, PCH Storage setting SATA mode Intel RST RAID premium optane, PCH Storage setting M2_1 controlled by RST, PCH Storage setting M2_2 controlled by RST
- boot from m2 appeared in boot options, but I still chose to boot from the existing boot disk
- with these settings, the PC bluescreened
- Secure boot setting had always been on "other OS", I activated CSM and then was able to boot normally as before
- in Windows storage manager, both NVMe disks are recognized, visible and formattable
- Intel RST still doesn't work
- Going back into the BIOS, I thought I would now try to make a RAID 1 volume.
- In the RAID configuration, only ONE NVMe disk is available for RAID, so I could not make a RAID volume
- Under "NVMe device configuration" it now says "No NVMe devices found"

 

Can someone please help me or point me to some documentation detailing the steps I need to take?
I imagine I'm not the only one who tried to do that.

For the life of me I don't understand why you would want to do this.  

It does not make sense.  

What do you hope to gain?

hmm.

maybe you can explain why it's a bad idea?

this box should become a high availability system.

 

RAID 1 has served me very well in the past against disk failure (the data backup is on other devices).

I admit my knowledge about UEFI / NVMe / Windows Secure Boot is limited, I would like to keep things as simple as possible regarding the NVMe RAID disks, ideally they should be readable on another system too.
