QM2-PCIE16XB01 is four M.2 (Socket 3 Key M PCIe-based SSD Module Pinout) to PCI Express x16 Bifurcation Adapter.

PCI Express bifurcation means splitting the PCI Express bus into smaller multi-slots . For example, one x16 PCI-Express Port can be bifurcated into four x4 PCI-Express Ports. This can be achieved from BIOS level if you want to split an existing lane.

QM2-PCIE16XB01 is a cost-effective and useful solution for installing multiple M.2 PCIe SSD Modules.

You can install four M.2 PCIe SSD Modules into the QM2-PCIE16XB01 then insert it into PCIe x16 slot on the computer.

Please be noted that your mainboard needs to have PCIe bifurcation mode (x4, x4, x4, x4) support.
