I am planning to buy 2 Crucial P3 Plus 1TB PCIe Gen4 3D NAND NVMe M.2 SSDs to use raid0 for MAG B760M MORTAR WIFI DDR4 motherboard. I wonder if it can use raid0?
Yes, but it's nonsense. Get one really good SSD instead (like WD Black SN850X, Samung 990 PRO), not two cheap/slow ones. Then it will run nice and fast, and you don't face potential complications later from using a RAID, where even a simple BIOS update can cause problems sometimes.
