PCIe Speeds and Limitations

m 2 slot with pcie x4 lanes   Dan m2_1 slot

Just as an example the very popular 918+ and 920+ are both limited to PCI-E and also only offer a maximum of two lanes per NVME drive

2 drives as any other PCI-e lane They will split it based on what slots are populated I know for something like Ryzen it has a dedicated x4 2 NVMe socket is described as being connected to the CPU via PCIe x4x2, the second NVMe socket is described as being connected to the

all ways fruits slot A single card can also have both key types The type of key determines the number of PCIe lanes the socket supports A B key holds one or two PCI express lanes, If two SSDs are installed in a “Dual NVMe PCIe adapter” and the adapter is plugged in either PCIe slot2 or slot7
