I have an old ASUS Rampage III Formula mobo with avaiable 16x PCIe slot. I believe it is still version 1. I am planning to install: ASUS Hyper M.2 X16 PCIe 4.0 X4 Expansion Card with Kingston NV1 2TB M.2 2280 NVMe PCIe Internal SSD. My question is: is this thing going to run at speed of 4 PCIe v1 lanes or at 16x PCIe v1 lanes? In other words, does the card distribute data across 16 lanes or just map 4 lanes to a drive?
