Windows 10: Storage Space on RAID not available

Windows 10 pro, just installed. Version 20H2. (Updates not yet started.) Two RAID 1 arrays created in BIOS MB: X570 AORUS Ultra, BIOS date Dec. 2019 I just installed Win10 Pro on the first RAID 1 (two M.2 drives). Windows cannot see the larger RAID 1 (SATA) I'd planned to use for data. Storage Spaces can see it and let me create a storage space on it, and it looks good there. PROBLEM: Windows cannot see this array/storage space. Neither does it show in Disk Management. Any ideas? Thanks!

Storages Spaces Configuration

I think I found the solution. It seems that there is a BUG in Storage Spaces. If you select Parity you cannot use the ReFS file system. The setup incorrectly allows you to select the ReFS file system after selecting Parity and then bombs out with the error
reported in my last post.

Through this process of starting down the Storage Spaces function two big road blocks for me were:

• The use of a RAID card. It seems that you cannot have any implementation, e.g. software or hardware, of RAID on the system if you want to use Storage Spaces on that system.
• If you want to use Parity you cannot use the ReFS file system.

Hopefully MS will fix the above issues.
