The sad part is Windows will have to be reinstalled if you change the BIOS to SATA and Windows was installed as RAID. The performance difference is not normally noticeable. 

If you really want both Windows 10 Pro and OpenSUSE - and keep the BIOS RAID - I would suggest installing VrtualBox in Windows 10 and loading OpenSUSE as a virtual machine in Windows 10. That way the Optane Windows performance will still be there for OpenSUSE - the speed difference on new hardware virtually vs running native is not but 4% (Unless you want games like Steam - they run better in Windows).  For virtual OpenSUSE - I suggest 40tb virtual drive and 4 gb ram and at least 2 CPU's - 4 if you have 8 threads. I have one 15.3. one 15.4 beta and a Tumbleweed VM all on my 1TB Intel 670 nvme on a Dell i5-8350 with 32gb ram and a Windows 10 VM and a Windows 11 VM (patched to allow no TPM).

My 2 cents.

Hi Larry, many thanks for your "2 cents" worth! ;-)  You set me off on an adventure poking around in all the dark corners of the BIOS (places I don't go) and I found (I think) the RAID setup/settings. Within the BIOS Configuration menu there is a sub menu titled UEFI HII Configuration (I have no idea what this is all about or why RAID setup would be there!). Under that I found a single sub-menu called Intel(R) Rapid Storage Technology (why not just call it RAID?) Opening that I get a menu titled (Intel(R) RST 17.8.0.4507 RAID Driver. Again there is yet another single item -  Optane Volume:  Intel Optane, 953.9GB. Opening that menu gives me yet another menu titled OPTANE VOLUME INFO. There it gives me a couple of non-settable bits of info - Disable mode:   Safe, and Size: 953.8GB. Next there is a toggle item that allows me to either Enable or Disable the Optane memory. It is set to show Disable meaning that the Optane memory is enabled, and clicking on it will disable the Optane memory and set the toggle button to show Enable.  Below that there is list titled Volume member disks: and there are two sub menu items, one for the Optane memory and the other for the SSD drive.

Opening up the SSD drive menu shows a number of non-settable info items -
Port:  4.0
Model Number:  INTEL HBRPEKNX0203AH
Serial Number:  TE034405TW1POC-1
Size: 953.8GB
Status:  Non-RAID
Controller Type: NVNe
Controller Interface: TG

Opening up the Optane drive menu also shows a number of non-settable info items -
Port: 5.0
Model Number:  INTEL HBRPEKNX0203AHO
Serial Number: TE034405TW1POC-2
Size: 27.2GB
Status: Cache
Controller Type: NVNe
Controller Interface: TG

My take is that the two "drives" are not set up as RAID drives.  Sorry for the wordiness but experience tells me it is best to be thorough and accurate when trying to explain things about computers. It is so easy for miscommunication!

I have not found any place where a drive can be set to SATA explicitly. But as you can see, AMI BIOS likes to hide things underneath lots of menu levels so I will keep looking.

The idea of using a VirtualBox under Windows sound intriguing, I know nothing about VirtualBox but will do some Googling to research it.

  HTHs,  Marc
