Green circuit board with four M.2 slots and silver heatsink

SMUGDESK

SMUGDESK PCIe X16 to 4-Port M.2 M-Key NVMe Expansion Card with Heatsink

SKU CH-9W5P-KNHZX

Converts a PCIe X16 slot into four M.2 NVMe ports with a built-in heatsink for stable multi-SSD operation

  • Converts one PCIe X16 slot into four independent M.2 M-Key NVMe ports for multi-SSD installation
  • Dedicated heatsink lowers operating temperature for continuous stable performance
  • Supports high-speed NVMe transmission to fully utilise each SSD
  • Compatible with PCIe X4, X8 and X16 slots on mainstream motherboards and servers
  • Plug-and-play design enables quick storage expansion for desktops, workstations and servers

Four M.2 NVMe ports from one PCIe X16 slot

This expansion card converts a single PCIe X16 slot into four independent M.2 M-Key NVMe ports, allowing multiple solid-state drives to run simultaneously. A dedicated heatsink helps maintain stable operating temperatures during sustained workloads. It fits standard desktop, workstation and server motherboards that provide a PCIe X16, X8 or X4 slot.

Suits storage expansion

Builders who need to add several NVMe drives without occupying extra expansion slots will benefit from the four-port layout and included cooling. Systems limited to fewer PCIe lanes or smaller form-factor slots cannot support the full port count and should consider alternative adapters.

Handles four NVMe SSDs at once

The card comfortably runs four M.2 NVMe drives in parallel, delivering high-speed storage capacity for demanding applications. Bandwidth per drive depends on the host platform's lane allocation, so configurations with fewer than 16 lanes will reduce per-port throughput.

Questions about this item

What motherboard slot is required to use the PCIe X16 to 4-Port M.2 NVMe expansion card?

The card requires an available PCIe X16 slot on the motherboard and is also compatible with PCIe X4 and X8 slots.

Will the expansion card work with PCIe 3.0 motherboards if I keep my current platform?

Yes, the card works with mainstream motherboards and servers, operating at the speed supported by the installed PCIe generation.

How can I confirm all four NVMe SSDs are detected after installing the card?

Check the system BIOS or UEFI and the operating system disk management utility to verify all four M.2 drives appear as separate storage devices.
