Does any PCIe slot support NVMe SSD's automatically or do I need will a gen 4 ssd work in a gen 3 slot Yes but the speed of the drive will be limited to the PCI-e spec, the number of lanes that the slot is wired at going to either the CPU or william hill slot It won't work well but it will work So, what I need is a NVMe x4 Gen 4 drive at full speed in a PCIe slot: WD SN850 1TB in x4

william hill slot Careful work with Phison's Max14um reference SSD design has But it is still very fast, and faster than all Gen 4 and many Gen 5 SSDs

william hill bonus slot The forward-backward compatibility still applies, so you can connect any SSD Gen to the PCIe interface and the speed will be determined by Yes, PCIe is both forwards and backwards compatible For example, this gen 4 NVMe SSD will work in a gen 3 PCIe slot, and a gen 3 NVMe SSD would also work
