Qnap QM2-2P-384A dual M.2 PCIe SSD expansion card

SKU CH-3M0Q-1J2JH MPN QM2-2P-384A

Adds two M.2 2280 or 22110 PCIe Gen3 x4 NVMe SSD slots via a PCIe Gen3 x8 host interface with a heatsink and smart fan, plus low-profile and full-height brackets

  • TypeType
  • Add two fast NVMe SSDs via dual M.2 slots
  • PCIe Gen3 x8 host link removes bandwidth bottlenecks
  • Heatsink plus smart fan prevents thermal throttling
  • Low-profile and full-height brackets fit any case
  • Qtier and SSD caching accelerate storage performance

Dual M.2 PCIe SSD Expansion Card

The Qnap QM2-2P-384A adds two M.2 slots to a desktop or server via a PCIe Gen3 x8 host interface. It accepts M.2 2280 or 22110 form factor NVMe SSDs running at PCIe Gen3 x4 speeds. A low-profile bracket is pre-loaded and both low-profile flat and full-height brackets are included for versatile installation.

Suits builders adding NVMe caching or tiered storage

This card targets users who want SSD caching and Qtier technology to accelerate existing volumes. It is not for systems lacking a PCIe Gen3 x8 slot. It is also not for anyone needing more than two M.2 devices or requiring a different host interface than the one provided.

PCIe Gen3 x8 host interface decides compatibility

The card requires an available PCIe Gen3 x8 connection to deliver full bandwidth to both NVMe SSDs. Without this specific slot the card will not operate as intended. Verify the motherboard or riser provides that exact link width before purchase.

Questions about this item

Will the PCIe Gen3 x8 host interface saturate before the two M.2 2280/22110 Gen3 x4 SSDs hit their peak sustained throughput?

The card provides a PCIe Gen3 x8 link to the host, matching the combined bandwidth of two M.2 Gen3 x4 NVMe drives so neither the slot nor the card becomes the first bottleneck under sustained load.

How loud is the smart fan and heatsink assembly when the card runs all day with two SSDs at full speed?

The manufacturer describes the cooling module as quiet, using a heatsink and smart fan to maintain sustained high performance without overheating.

What motherboard slot and bracket height do I need to install this expansion card?

The card uses a PCIe Gen3 x8 host interface and ships with a low-profile bracket pre-loaded plus low-profile flat and full-height brackets in the box.
