M.2 NVMe PCIe 3.0 X4 to U.2 Adapter
The SMUGDESK PH416 adapter card converts an M.2 NVMe or SATA SSD into a 2.5-inch U.2 SFF-8639 drive. It is designed for PC and server builders who need to install an M.2 module into a U.2 bay or backplane.
Dual B/M Key Support and 6Gbps Transfer
The card accepts B-key and M-key M.2 modules in 2230, 2242, 2260 and 2280 lengths. A 6Gbps transmission rate provides stable read and write performance for everyday storage workloads.
Check M.2 Key Type and U.2 Bay Availability
Verify that your M.2 SSD uses a B or M key before ordering. Ensure the target system has a free 2.5-inch U.2 SFF-8639 connector and sufficient physical clearance for the adapter card. Buyers needing direct PCIe slot mounting or support for other M.2 key types cannot use this product.

Questions about this item
What PCIe generation and lane width does the PH416 adapter use, and what practical throughput does that cap at?
The adapter runs on PCIe 3.0 X4, which limits real-world throughput to 6Gbps for the connected U.2 drive.
What physical space and mounting does the PH416 require to fit a 2.5-inch U.2 SSD?
It needs a standard PCIe slot on the motherboard and a 2.5-inch drive bay or bracket to secure the U.2 SSD.
How is the PH416 installed, and which step do people often get wrong?
Insert the card into a PCIe slot, mount the M.2 SSD onto the onboard B/M key socket matching its length (2230 to 2280), then connect the U.2 cable; the common mistake is not securing the M.2 screw for the specific SSD size.
