Overview

The QNAP TS-873AeU-4G is an 8-bay 2U rackmount NAS engineered for small-to-medium businesses that need enterprise-grade storage without the footprint of a full-depth server. Powered by the AMD Ryzen Embedded V1500B — a quad-core, eight-thread processor running at 2.2 GHz — it delivers the processing headroom required for simultaneous file serving, virtualization via QNAP's Virtualization Station, and container-based applications. The dual 2.5GbE ports support link aggregation for increased throughput or failover for reliability, while the PCIe Gen 3 x8 expansion slot opens the door to 10GbE networking, M.2 NVMe SSD caching via QM2 cards, or additional USB 3.2 Gen 2 connectivity running at up to 10Gb/s.

QNAP's software ecosystem adds significant value to the hardware. Boxafe provides automated backup for Google Workspace and Microsoft 365 accounts, QVR Pro delivers comprehensive 24/7 surveillance camera management, and QNAP's snapshot-based ransomware protection safeguards critical data against encryption attacks. The short-depth chassis design at approximately 19 inches makes it practical for network closets, branch offices, and edge deployments where standard rack depth is unavailable. While the base 4GB DDR4 RAM configuration is adequate for basic file serving, the ability to expand to 64GB means the TS-873AeU can grow alongside your organization's demands — from a straightforward file server to a full virtualization and application platform.

Pros & Cons

👍 Pros

  • AMD Ryzen Embedded V1500B quad-core processor delivers strong performance for virtualization and multi-user access
  • Short-depth 2U rackmount design fits in space-constrained racks and network closets
  • RAM is expandable from 4GB up to 64GB DDR4 to grow with workload demands
  • Dual 2.5GbE ports provide link aggregation or failover without requiring add-in network cards
  • PCIe Gen 3 x8 expansion slot allows customization with 10GbE, NVMe caching, or USB cards

👎 Cons

  • Ships with only 4GB RAM which is minimal for virtualization or heavy multi-user workloads and will likely need upgrading
  • Dual 2.5GbE networking may be insufficient for environments that require 10GbE baseline speeds
  • At 16.74 pounds the unit has significant weight that requires proper rack support
  • No built-in 10GbE port means additional expense for high-speed networking via the PCIe slot
