Overview

The QNAP TS-473A-8G is a four-bay desktop NAS built around an AMD Ryzen V1500B quad-core processor clocked at 2.20 GHz, paired with 8GB of DDR4 RAM. This hardware configuration positions it well above entry-level NAS devices, delivering enough processing headroom to run virtual machines, Docker containers, surveillance camera feeds, and media transcoding services alongside everyday file storage and backup duties. The tower form factor keeps the unit compact enough for a desk or shelf deployment, making it practical for home offices, small businesses, and creative professionals who need centralized, high-performance storage without rack infrastructure.

Networking is handled through dual 2.5 Gigabit Ethernet ports, which provide a meaningful throughput improvement over standard Gigabit connections and can be configured for link aggregation to further increase bandwidth for multi-user environments. The four SATA bays accept both 3.5-inch and 2.5-inch drives and support a range of RAID configurations including RAID 0, 1, 5, 6, 10, and JBOD. QNAP's QTS 4.5.1 operating system delivers a browser-based management interface with access to a broad library of installable applications, covering everything from automated backups and cloud sync to media streaming and development tools. The expandable RAM slots allow users to increase memory as their workloads grow, extending the useful life of the system well beyond its initial deployment.

Pros & Cons

👍 Pros

  • AMD Ryzen V1500B quad-core processor handles multitasking, virtualization, and surveillance workloads efficiently
  • 2.5 Gigabit Ethernet ports deliver faster transfer speeds than standard Gigabit without requiring expensive 10GbE switches
  • 8GB DDR4 RAM is expandable, allowing you to scale performance as demands grow
  • QTS operating system provides a full app ecosystem including virtualization, containers, and multimedia services
  • Tower form factor runs quietly and fits easily on a desk or shelf without rack hardware

👎 Cons

  • Four drive bays may be limiting for users who anticipate needing more than four drives for large storage pools
  • No built-in SSD cache slots separate from the main bays, so adding cache drives reduces available HDD bays
  • Does not include any hard drives, which adds to the total cost of getting the system operational
  • Fan noise under sustained heavy load can become noticeable in quiet home office environments
  • The QTS interface has a learning curve for users who are new to NAS administration

Frequently Asked Questions

The TS-473A has four drive bays that accept both 3.5-inch and 2.5-inch SATA drives. Maximum capacity depends on the size of the drives you install — with four 20TB drives, for example, you would have up to 80TB of raw storage before RAID configuration.
Yes, the TS-473A supports DDR4 RAM upgrades. It has two SO-DIMM slots, and you can expand the memory to increase performance for virtualization, multiple concurrent users, or demanding applications.
The TS-473A supports multiple RAID levels including RAID 0, 1, 5, 6, 10, and JBOD, giving you flexibility to prioritize performance, redundancy, or a balance of both depending on your needs.
Yes, the AMD Ryzen processor and 8GB of RAM make it capable of running virtual machines via QNAP's Virtualization Station and Docker containers via Container Station, both available through the QTS app center.
The 2.5GbE ports provide 2.5 times the throughput of standard Gigabit Ethernet, allowing faster file transfers and smoother multi-user access without requiring a full 10GbE infrastructure upgrade.
