PCIe vs PCIe NVMe SSDs: What's the difference?

Curious why my Intel 660p SSD only gets one lane when is supposed to be provisioned with 4 lanes socket checked and fine,

If its Intel, there are only 16 PCI-E 5 lanes on the CPU, so using a 4x slot switches the GPU slot slot to 8x gen 5 But there aren

m2 sata vs nvme slot You can have one, four, eight or sixteen lanes in a single PCIe slot, denoted as x1, x4, x8, or x16 PCIe bandwidth can be scaled up to 16

m2_1 slot This 2-in-1 SSD PCIe Adapter is a multi-functional NVMe conversion card, which can support the PCIe protocol NVMe SSD to connect directly to the
