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.
