Review on 💥 ASUS Hyper M.2 X16 PCIe 4.0 X4 Expansion Card: Supports 4 NVMe M.2 (2242/2260/2280/22110) up to 256Gbps, Compatible with AMD 3rd Ryzen sTRX40, AM4 Socket, and Intel VROC NVMe Raid by Ken Martinez

One click in the bios and a 16x PCIe slot becomes 4 x 4x M.2 slots. Everyone is visible to the BIOS and Windows 10. You will get 4 M.2drive headers with heatsinks and stabilized power supply. All 4 are CPU lanes and do not pass through common CPU lanes from the PCH (chipset). This can be a single drive letter in RAID 0 or 4 drive letters as separate drives. 2 M.2 drive slots are available for you in the 8X PCIe slot. On the new board with GEN4 lanes you get a whopping 32 GB of bandwidth per drive. Yes, this is for GEN4 drives. Yes, it works with GEN4 drives on older GEN3 mobile devices. It works for me on Zenith Extreme and is ready for the new Zenth II Extreme Alpha. UPDATE: I couldn't expand my 2TB boot drive to a single 8TB drive, but I was able to use D drives. E; Q: per 6TB combo drive. Very easy in W10, and new downloads can be placed in the new D; Drive.
