Lets dig this quite old thread out.


I have read that those qnap dual/quad m.2 nvme cards work also on non qnap systems. They also say they have a pcie switch on board. Anyone have tried those? I am going to to try the cheapest one QM2-2P-244A -> 2xnvme on a pcie gen2 x4

They also have gen3 with x8 interface up to 4 nvme drives. All say they have pcie switch on board. Maybe this switch means they dont rely on cpu/mobo bifurcation?

Having a PCIe switch chip onboard is designed to take care of the bifurcation issue.

Unfortunately, the PCIe switch chips are not always compatible with PCIe bus controllers. So they need to be tested.

Buy from someone with a good return policy.
