Detailed Specifications

QNAP TS-873 SAN/NAS Storage System - AMD R-Series RX-421ND Quad-core (4 Core) 2.10 GHz

Affordable high-end AMD RX-421ND quad-core NAS with PCIe slots for adding M.2 SSD, 10GbE connectivity, and a graphics card
The TS-873 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-873 as a wireless access point; and an entry-level graphics card (for example: NVIDIA® GeForce® GT1030) to boost system performance for 4K video performance. The TS-873 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 the NVIDIA® GeForce® GT1030 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.

Greater NAS potential with two PCIe slots The TS-873 features two PCIe (Gen3 x4) slots, allowing for installing single/dual-port 10GbE NICs to accelerate applications that demand higher bandwidth such as virtualization, media workflows, and backup/restoration tasks for an ever-growing amount of data; or a USB 3.1 Gen2 (10Gb/s) expansion card for transferring large media files to and from USB storage. You can also install QM2 cards, wireless network cards or an entry-level graphics card to extend NAS functionality. AMD R-Series quad-core CPUEquipped with a next-gen AMD R-Series RX-421ND quad-core 2.1 GHz CPU (Turbo Core up to 3.4 GHz) with up to 64GB dual-channel DDR4 RAM, the TS-873 enables lightning-fast multi-tasking with low power consumption for up to 2379 MB/s throughput with a 10GbE configuration. With a hardware-accelerated AES-NI encryption engine, the TS-873 also provides unmatched encryption performance in its class (up to 2332 MB/s with AES 256-bit full NAS volume encryption) to boost system performance while ensuring the safety of sensitive business data stored on the NAS. Top-class hardware engineering The strong and feature-packed hardware bolsters overall system performance. Coupled with a flexible and expandable architecture, the TS-873 can fulfill diverse application needs. SSD caching and 10GbE connectivity The TS-873 supports the innovative QM2 PCIe card that allows for adding up to two M.2 SSDs. You can configure SSD caching, or create a RAID 5 tiered storage along with the two M.2 SSDs in the NAS. As these M.2 SSDs will not occupy any 3.5-inch drive bays, the QM2 card allows you to maximize both your storage capacity and performance. There are also QM2 cards that include 10GbE 10GBASE-T connectivity to provide SSD caching with high-speed network connectivity on a single card.
