QM2 Expansion Card

(Add M.2 SSD Slots)

Flexible and versatile, boosts performance and functionality


QM2 series PCIe cards add support for M.2 SSDs to a QNAP NAS, allowing users to configure SSD caching, a caching pool, or an auto-tiering volume to improve overall NAS performance.



Tackle performance bottlenecks

QM2 boosts performance by adding M.2 SSDs. It doesn’t occupy any 3.5-inch drive bays, allowing you to maximize both your storage capacity and performance. 



  • M.2 SSDs* can be installed to form caching pools or an auto-tiering volume.
  • Enables SSD caching to boost performance and optimizes storage efficiency with Qtier Technology.
  • M.2 SSD thermal sensors allow real-time M.2 SSD temperature monitoring.
  • A quiet cooling module (heatsink and smart fan) minimizes overheating risks and sustains constant high performance.
  • LED indicators for monitoring M.2 SSD status.

* M.2 SSDs are not included as standard
