The TS-473 is powered by a high-performance and energy-efficient AMD R-Series CPU and provides two PCIe slots for greater functionality. You can install a QNAP QM2 expansion card to add M.2 SSD caching/10GbE connectivity; a compatible wireless card to use the TS-473 as a wireless access point; and an entry-level graphics card to boost system performance for 4K video performance. The TS-473 allows you to flexibly deploy a wide range of applications with a more affordable budget.

  • Two PCIe Gen3 x4 slots support QM2 cards, 10GbE adapters, or wireless network cards.
  • Supports entry-level graphics card, allowing for 4K video transcoding and output.
  • Dual M.2 SATA 6 Gb/s SSD slots allow for setting up caching or storage pools, improving file access efficiency.
  • Qtier auto-tiering technology and SSD caching enable 24/7 optimized storage efficiency.
  • Scalable storage supporting virtualization, containerized apps, centralized storage, backup, sharing, and disaster recovery.
  • Snapshots fully record system status and data. If files are accidentally deleted or modified, you can quickly restore the data from a snapshot.

Use only QNAP memory modules to maintain system performance and stability. For NAS devices with more than one memory slot, use QNAP modules with identical specifications.
