SMUGDESK PH46-2 PCIe 4.0 X8 Adapter
The SMUGDESK PH46-2 is a hard drive adapter that adds dual SFF8639 U.2 NVMe ports and a 2.5-inch SATA port to a system via a PCIe 4.0 X8 slot. It supports X4X4 bifurcation for simultaneous drive operation and remains backward compatible with PCIe 3.0. Gold-plated contacts provide stable signal transmission for servers and workstations.
For multi-drive NVMe and SATA expansion
This card suits builders who need to run two U.2 NVMe drives alongside a 2.5-inch SATA device from a single X8 slot. It is not for systems lacking PCIe bifurcation support, as the dual U.2 ports will not function independently without it. Buyers requiring M.2 slots or additional SATA connectors should look at other adapters.
PCIe 4.0 X8 with X4X4 bifurcation
The decisive specification is the PCIe 4.0 X8 interface combined with X4X4 lane split capability. This configuration determines whether two U.2 NVMe drives can operate at full speed simultaneously. Verify that your motherboard supports bifurcation on the target slot before purchase.

Questions about this item
Will this card fit in my PCIe 3.0 motherboard slot?
The card uses a PCIe 4.0 X8 edge connector and is backward compatible with PCIe 3.0, so it will operate at 3.0 speeds in an older slot.
How can I confirm both U.2 NVMe drives are running at full speed?
Check your motherboard BIOS or OS disk utility to verify each drive negotiates a PCIe 4.0 X4 link; the card splits the X8 lane into two X4 paths.
What cables or drives must I supply to use the SATA and U.2 ports?
You provide the 2.5" SATA drive or SSD and its data cable, plus up to two U.2 NVMe drives; the card has the SFF-8639 connectors and a 2.5" SATA port onboard.
