Is it possible to set up a RAID with NVMe drives in slots 3 and 4?

I have a MAG Z790 Tomahawk MAX WiFi Gaming motherboard and want to create a RAID using the NVMe drives in slots 3 and 4. My Windows 11 OS is installed on the NVMe drive in slot 1 and is running fine. Can I set up this RAID without affecting my OS drive? Also, is it possible to RAID SATA drives together?

You can set up a RAID with NVMe drives in slots 3 and 4 on the MAG Z790 Tomahawk MAX WiFi motherboard without affecting your Windows 11 installation on slot 1, as long as the OS drive is not included in the RAID.

The motherboard supports Intel RST (Rapid Storage Technology) RAID for NVMe drives. You can create the RAID array through the BIOS or using the Intel RST utility in Windows. Check the motherboard manual for lane sharing, since some NVMe slots share PCIe lanes with SATA ports, which could disable certain ports if not configured correctly.

With two NVMe drives, you can choose:

RAID 0 (striping): Faster performance, no redundancy. If one drive fails, all data is lost.

RAID 1 (mirroring): Data is duplicated on both drives. One drive can fail without losing data.

SATA drives can also be configured in RAID using Intel RST. The same options apply depending on the number of drives.

Because your OS drive is separate, creating a RAID on slots 3 and 4 will not affect Windows 11.
