is RAID1 surely not supported by PRIME B660M-AWIFI D4 motherboard by PCIe 2x NVMe SSD ?

[SWADE]

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 ?

Hello @SWADE 

Thank you for reaching out to us.
According to the PRIME B660M-A WIFI D4 specifications page and the user manual, we confirm that the PRIME B660M-A WIFI D4 supports SATA RAID only and does not support NVMe RAID.

If you require RAID functionality, please purchase hard drives that match the supported specifications.
For setup instructions, please refer to page 66 of the BIOS manual and the guide on [Motherboard] How to Create Intel 600 or 700 Series MB RAID in BIOS Setup.

Thank you.
