Green circuit board with two M.2 slots and a PCIe x16 connector

RIITOP

RIITOP Dual NVME M.2 PCIe 4.0 Expansion Card

SKU CH-2PDW-JBEJ8

Adds two NVME M.2 drives via a PCIe 4.0 slot, requiring motherboard bifurcation for both drives to be recognised

  • Product typeNVME to PCIe 4.0
  • Dual NVME drives run simultaneously at full speed
  • Requires motherboard PCIe bifurcation for both drives to be recognised
  • Soft RAID supported under Windows 10 with third-party software
  • Built-in high-power DC modules deliver stable power
  • Install in primary PCIe x16 slot for best compatibility

Dual NVMe M.2 PCIe 4.0 Adapter

This RIITOP expansion card installs two M-key NVMe solid-state drives into a single PCIe slot. It requires a motherboard that supports PCIe bifurcation so each drive receives a full x4 electrical link. The board includes high-power DC modules for stable simultaneous operation. It is built for enthusiasts adding fast local storage to a desktop platform.

Suits systems with bifurcation support

Builders whose motherboard firmware can split a x16 or x8 slot into x4/x4 lanes can run both drives at full speed. Windows 10 software RAID or third-party tools are needed for RAID 0 arrays; no hardware RAID controller is present. Boards lacking bifurcation will detect only one drive, making this card unsuitable for those platforms.

Requires PCIe bifurcation

The single specification that decides compatibility is whether the target slot can be configured for x4/x4 lane splitting in the BIOS or UEFI. Without that capability the second M.2 socket remains invisible to the system. Verify the motherboard manual for bifurcation options before purchase.

Questions about this item

Will both NVME drives hit full speed under sustained load without throttling?

The card includes high-power DC modules designed for stable operation with both NVME drives running at full speed simultaneously.

How much power and heat does the adapter generate when both drives run all day?

Built-in high-power DC modules supply each NVME drive continuously; the card itself has no active cooling, so case airflow must handle the drives' heat.

What motherboard feature is required before this card can recognise both NVME drives?

The motherboard must support PCIe bifurcation (x4/x4 or x4/x4/x4/x4) in the slot used, otherwise only one NVME drive will be detected.
