NVME RAID not working

[walkalone]

ROG STRIX B550-F GAMING BOARD.   Attempted to implement RAID using two SK hynix Gold P31 1TB PCIe NVMe Gen3 M.2 2280 Internal SSDs.  I configure a RAID array like RAID 0 or RAID 1.  No matter which RAID I choose, the RAID array evaporates when system reboots to install Windows 10 or 11.  

Normally, when RAID is implemented, the RAID array is not visible until you load RAID driver in the middle of the Windows installation process.  However, when I come to the step where I choose the drive on which I install the Windows, I already see the two NVMe drives.  So, if I go back to BIOS to look at RAID info, I discover that the RAID array I created is gone, and the two NVMe drives are shown as non-raid drives.  

ASUS has got to fix this problem.

Anyone had the same type of problem?

Hello, @walkalone 

After confirming the RAID configuration and related settings, setting it to RAID 1 indeed mirrors the storage of data, hence having two separate drives should be the correct option.
RAID 0: (Data striping) optimizes two identical hard disk drives to read and write data in parallel, interleaved stacks.
RAID 1: (Data mirroring) copies and maintains an identical image of data from one drive to a second drive.
If needed, you can change the settings to RAID 0, which will leave you with only a single drive.

Thank you.

You are very wrong about RAID 1.  Any RAID array you create in BIOS shows up as single storage to the operating system. 

I think you should stop trying to help others, especially regarding RAID issues.
