Low-profile PCIe card with four M.2 slots, aluminium heatsink and adjustable fan

SMUGDESK

SMUGDESK PH44PLUS PCIe 4.0 x16 to 4×M.2 NVMe RAID Card

SKU CH-K2NP-90ZGZ

PCIe 4.0 x16 card splits into four M.2 NVMe slots with RAID 0/1/10 support and active cooling for 2U servers

  • Four M.2 NVMe slots accept 2242 to 22110 drives
  • PCIe 4.0 x16 delivers 4×32Gbps total bandwidth
  • Hardware RAID 0/1/10 with boot support and VROC compatibility
  • Low-profile dual-sided design fits 2U servers with active cooling
  • Gold-plated contacts and thick PCB ensure stable plug-and-play operation

Four M.2 NVMe Slots on One Card

The PH44PLUS converts a single PCIe 4.0 x16 slot into four M-Key NVMe ports. It accepts 2242, 2260, 2280 and 22110 form factors for RAID 0, 1 or 10 arrays. Boot support is included when the motherboard provides PCIe bifurcation.

Active Cooling for 2U Density

A low-profile dual-sided layout fits 2U rackmounts and adds an adjustable turbo fan plus an aluminium heatsink. Four activity LEDs show real-time drive status without software. Gold-plated contacts and a thick PCB with high-power DC regulators keep power delivery stable under load.

Check Bifurcation and Clearance

The card needs a motherboard that can split a x16 link into four x4 links for RAID to function. Intel VROC and AMD NVMe RAID both require that bifurcation. Verify your chassis can accommodate the dual-sided design and fan height before ordering.

Questions about this item

Does the onboard turbo fan and heatsink need periodic cleaning or replacement?

The card includes an adjustable-speed turbo fan and aluminum heatsink; dust buildup can reduce airflow, so occasional cleaning with compressed air keeps cooling effective.

Which component reaches its thermal limit first when all four slots run sustained PCIe 4.0 x16 bandwidth?

The M.2 NVMe SSDs themselves hit thermal throttling before the card's VRM or fan curve, especially in a 2U chassis with restricted airflow.

How much power does the card draw and how loud is the fan under continuous 128 Gbps RAID 0 load?

The card draws auxiliary power from the PCIe slot plus onboard DC regulators; the adjustable turbo fan ramps up under load but runs quieter at lower SSD temperatures.
