Its been five years since last build. would like to use raid 1 mirroring. have two matched SAMSUNG PM9A1V-NAND 2280 SSD PCIe NVMe Gen 4 that are going in my ASUS ROG Maximus Z790 Hero. Is the fastest connection to use the provided ROG hyper M.2 card in the lowest PCI slot on the MB? it seem the 2280 leanth cards will only fit there. thanks
