Review on 📈 ASUS Hyper M.2 X16 PCIe 3.0 X4 Expansion Card V2: Boost Your NVMe Storage with Intel VROC and AMD Ryzen Threadripper NVMe Raid Support by Robert Ewing

Product works very well. V2 adds a second phase of performance in case you're wondering. I have both versions and they work fine. You just need to know if your motherboard supports X4X4X4X4 or X4X4 bifurcation for four or two drives respectively. This will most likely be difficult if you are using a dedicated graphics card with a desktop setup. If you are using onboard video this should be fine, or use it in a HEDS X399/X299 setup where you have available PCIE lanes.
