Green circuit board with two U.2 SFF-8639 slots and PCIe x16 edge connector

LORDWORLD

LORDWORLD Dual U.2 SFF-8639 PCIe 3.0 x8/x16 Adapter

SKU CH-4ND1-V5P57

Connects two U.2 SFF-8639 SSDs via PCIe 3.0 x8 or x16 lanes, requiring motherboard lane bifurcation for both drives to operate at full speed

  • Runs two U.2 drives at full speed simultaneously
  • Requires motherboard with PCIe bifurcation to detect both drives
  • No hardware RAID — Windows 10 virtual RAID or third-party software only
  • High-power DC modules deliver sustained stable operation
  • Fits two U.2 SFF-8639 drives in a single slot

Dual U.2 SFF-8639 PCIe 3.0 Adapter

This adapter connects two U.2 SFF-8639 solid-state drives to a single PCI Express 3.0 slot. It is built for workstations and servers that need high-density enterprise storage without occupying multiple expansion slots. The board includes high-power DC modules to sustain both drives under continuous load.

Requires motherboard PCIe bifurcation

The card only functions with motherboards that support detachable PCI-E channels for signal splitting; boards without this feature will recognise only one drive. Hardware RAID is not supported, so users needing a dedicated RAID controller should look elsewhere. Virtual RAID is possible under Windows 10 or via third-party software.

Fits one x8 or x16 slot

Installation consumes a single PCIe 3.0 x8 or x16 slot and draws auxiliary power through onboard DC modules rather than drive bays. This frees internal 2.5-inch or 3.5-inch bays for other devices while delivering full-speed operation to both U.2 drives simultaneously.

Questions about this item

What motherboard feature is required for both U.2 ports to be recognised?

The motherboard must support PCIe lane bifurcation so the x16 slot can split into two x8 links; without it only one drive will appear.

Can I combine the two U.2 drives into a single volume using this adapter alone?

No hardware RAID is present; you must create a virtual RAID in Windows 10 or use third-party software to stripe the drives.

How do I verify each U.2 SSD is running at PCIe 3.0 x8 speed after installation?

Check the link width and generation in Device Manager or a tool such as HWInfo — each drive should show Gen 3.0 x8 when both are active.
