QNAP QM2‑4P‑384 Quad M.2 2280 PCIe Gen3 x8 NVMe SSD Expansion Card

The QNAP QM2‑4P‑384 is a high‑performance PCIe expansion card designed to add four M.2 NVMe SSD slots (M.2 2280) into a compatible PC, workstation or NAS system. With a PCIe Gen3 x8 host interface and active cooling (heatsink + fan), it allows for SSD caching, SSD volume creation or tiered storage with no sacrifice of drive bay space. :contentReference[oaicite:1]{index=1}

Key Features

• Four NVMe slots: 4 × M.2 2280 PCIe (Gen3 x4) NVMe SSD slots. :contentReference[oaicite:2]{index=2}
• Host interface: PCIe Gen3 x8 for the expansion card. :contentReference[oaicite:3]{index=3}
• Cooling solution: Built‑in heat sink plus smart fan for thermal control and sustained performance. :contentReference[oaicite:4]{index=4}
• Bracket support: Low‑profile by default, includes flat low‑profile and full‑height brackets. :contentReference[oaicite:5]{index=5}
• Applications: Ideal for SSD caching, Qtier tiering, high‑IOPS workloads (e.g., editing, VMs), especially in NAS or PC/Server systems. :contentReference[oaicite:6]{index=6}

Why Choose the QM2‑4P‑384?

• Allows substantial performance uplift by adding four NVMe SSDs in systems where standard drive bays are limited or in use.
• Great for caching, tiered storage or high‑throughput/low‑latency workloads—especially useful in NAS environments where NVMe caching can improve random I/O dramatically.
• Supports compact installation (low‑profile bracket options) and includes thermal management to sustain NVMe performance.

Compatibility & Considerations

• Ensure your system has a free PCIe slot that supports at least PCIe Gen3 x8 to take full advantage; using fewer lanes may bottleneck performance. :contentReference[oaicite:12]{index=12}
• Check the M.2 SSD compatibility list from QNAP (and your system) as some NVMe models or firmware versions may not be supported. :contentReference[oaicite:13]{index=13}
• In NAS setups, verify the PCIe slot specification and zone requirements (e.g., some TS‑x77 or TVS‑x82(T) series may restrict QM2 card to certain slots). :contentReference[oaicite:14]{index=14}
• Cooling and airflow are important—NVMe SSDs produce heat under sustained load, and card's built‑in fan should be unobstructed. :contentReference[oaicite:15]{index=15}
