Windows 10: Disbanding RAID-arrays in Storage Spaces

I recently had to disband a RAID5-array in storage spaces and noticed, that it obviously had to be formatted/data deleted in order for that to happen. I was just wondering whether this would also be the case with a RAID1 by some Microsoft logic, or if I can actually keep the data on the individual drives when disbanding since it's just two copies of data?

:)

 

Can I use a RAID 1 drive array as my Windows boot drive?

I am not going to use hardware RAID. I want to use Windows Storage Spaces to create the RAID 1 array from two identical hard drives.

Do I install Windows on the first hard drive then create the RAID array using Storage Spaces?

When I create the RAID array will Windows automatically mirror the Windows installation including the boot partition to the second drive so the RAID array is bootable?

Are their any steps unique to this setup that I must follow when installing Windows or creating the RAID array so that the RAID array will be bootable?

 

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!

 

Recreating RAID 5 Array AMD


Poked around in the AMD RAIDXpert utility (didn't have to use it with W7) and it will let me make a RAID 0, 1, or just a bunch of disks array but not RAID 5 or 10. Mobo is an Asus M4A79T Deluxe that has an AMD SB750 RAID controller that supports RAID 0,1, 5, and 10. If nothing else I could go with a RAID 1 array with a hot spare and have fault tolerance but I'd prefer to get RAID 5 working for both the performance and fault tolerance.

Found How To Set Up a RAID 5 Array in Windows 8 and Linux - Maximum PC and it seams like this might be the same as doing a RAID 5 array according to Storage Spaces: FAQ - Windows Help
. I know I never had to use it in W7 to create the array I just defined it in the controller and then in disk management it showed up as a single unallocated drive with ~1.8TB of space. Now when I define the array in the controller I still see the 3 separate disks one 1 unallocated, 1 uninitialized, and 1 offline in disk management.

EDIT: looks like storage spaces is a software RAID utility and since the mobo supports RAID 5 via hardware it would be better to figure out why its not allowing me to create the RAID 5 array.
