Green circuit board with four M.2 slots and gold PCIe x16 edge connector

SMUGDESK

SMUGDESK PCIe 4.0 X16 to 4-Port M.2 NVMe Adapter Card 2280

SKU CH-YCV6-459CV

Converts one PCIe 4.0 X16 slot into four M.2 2280 NVMe ports with bifurcation and RAID support

  • Converts one PCIe 4.0 x16 slot into four M.2 NVMe ports
  • Supports M.2 2280 NVMe SSDs for mainstream storage expansion
  • Enables PCIe bifurcation and RAID array configuration
  • Backward compatible with PCIe 3.0 motherboards
  • Plug-and-play installation for desktop and server systems

Four-Port NVMe Expansion

This SMUGDESK adapter converts a single PCIe 4.0 X16 slot into four independent M.2 NVMe ports. It accepts 2280 form factor SSDs for high-capacity storage arrays. The card supports PCIe bifurcation and NVMe RAID modes for flexible configuration. It is built for desktop and server platforms needing dense flash expansion.

Bifurcation Dependent

Suits builders whose motherboard firmware exposes PCIe bifurcation options for the X16 slot. RAID functionality also requires platform support for NVMe arrays. Not suitable for systems lacking bifurcation control, as the four ports will not appear independently. Buyers needing a single drive upgrade should consider a direct M.2 slot instead.

PCIe 4.0 X16 Interface

The card requires a physical X16 slot wired for PCIe 4.0 or 3.0 operation. Bandwidth scales with the host generation, delivering up to 4.0 speeds when the platform supports it. Verify slot wiring and BIOS bifurcation settings before purchase. Without an X16 link, the adapter cannot function.

Questions about this item

Does the PCIe 4.0 x16 adapter card need active cooling when running four NVMe SSDs all day?

The card has no onboard fan; sustained loads on four drives will rely entirely on case airflow, so ensure good front-to-back ventilation.

Must my motherboard support PCIe bifurcation to use all four M.2 2280 slots?

Yes, full four-drive operation requires a CPU and motherboard that can split the x16 link into four x4 lanes; without bifurcation only the first slot is active.

Will my existing PCIe 3.0 motherboard run this card at reduced speed?

The card is backward compatible with PCIe 3.0, so it will work, but each NVMe SSD will be limited to PCIe 3.0 x4 bandwidth instead of 4.0 speeds.
