I spent $4000 buy a desktop PC coming with ASUS PRIME B660M-AWIFI D4 motherboard, I wanted to build RAID 1 with OS redundancy (Windows 11 Pro), so I purchased 2x PCIe 4.0 NVMe SSD(WD SN580) under the reseller's recommendation.
However, when I got home trying to setup the RAID1 from BIOS, it showed the picture attached - unable to type in the volume size to create RAID1 volume, with "PCIe Raid Volumes not supported".
I urgently want to know - is RAID1 surely not supported by PRIME B660M-AWIFI D4 motherboard by PCIe 2x NVMe SSD ?
