4 * NGFF Key-M NVMe Slot To PCI Express PCl-E 16X

So, the PCIe or third-generation card will function when installed in a PCIe or second-generation slot as the PCIe standard is such that it is both

Limiting it to PCIe x4 merely halves the maximum bandwidth, so the linear thruput will be lower But very rarely do you have long, linear

nvme in pcie slot As the subsequent iteration of Gen3, Gen4's data transfer rate is twice that of PCIe Gen 3, enabling PCIe Gen 4 devices to transfer data at a faster speed

nvme vs m2 slot All PCIe Generations slots and slots are backward compatible so there is no need to worry about purchasing the wrong expansion card or NVMe SSD But you
