PCIe vs NVMe: What's the difference?

Will installing a 2nd SSD compete PCIe bandwidth with GPU m 2 slot with pcie x4 lanes Additional CPU PCIe lanes give both your GPU and SSD access to CPU lanes 2 SSDs use x4 lanes Each generation of PCIe is twice as fast as its m2 slot I bought the adata drive knowing that both slots support pcie x4 This is really frustrating since I expected at least 2900 read speed 0

m2 nvme slot Generally speaking, the number of lanes supported by a PCIe device is represented as follows: x4 means 4 lanes, and x8 means 8 lanes Taking the ADATA
