My M.2 drive is the Samsung 970 PRO NVMe (2280 design from what I read). My Maximus Extreme XI has 2 M.2 slots. M.2_1 supports PCIe 3.0 x4 and Sata mode M key design. M.2_2 supports PCIe 3.0 M key design. Both of these fit the 2280 design for my 970 PRO but I’m not sure if these take bandwidth from my sata ports. I’m also not sure which one would take best advantage of the 970 PRO. I am a bit new to the M.2 game here so go easy on me and I thank anyone stopping by to help me. This has been a nice community to me throughout the years.
