Add two M.2 NVMe SSDs to your NAS with a PCIe 3.0 expansion card.  PCIe 3.0  PCIe Gen 3 x4 provides up to 32 Gbps transfer speeds to your NAS.  Ready-to-use  No drivers or extra software are required.      SSD cache & volume  Configure SSD caching, an SSD volume, or Qtier (QNAP’s auto-tiering technology) to improve overall NAS performance.      Efficient cooling module  Keeps your SSDs cool and maintains high performance.  Tool-less design  Easily install M.2 SSDs in your NAS with a screw-less, easy-to-use locking method.  LED indicators & thermal sensors   Monitor the real-time status and temperatures of the M.2 SSDs.  Fast, efficient, and easy-to-use  The efficient architecture of the QM2-2P-344A allows you to easily install NVMe SSDs and maximize their performance with a quiet cooling module.  SSD caching  Enable SSD caching to optimize system performance and reduce I/O latency. Caching is especially ideal for IOPS-demanding applications such as virtual machines and systems with a large number of small files.  Qtier  Alternatively, you can set up Qtier auto-tiering to your NAS to improve overall system performance and maximize storage utilization.  Keep SSD cool  A quiet cooling module (heatsink and smart fan) keeps your SSDs running with dependable high performance.  Super-fast NVMe SSD storage volume  Photographers and videographers can tackle high-resolution RAW multimedia editing directly on NVMe SSD volumes. RAID configurations can help prevent data loss from drive failure.
