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 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.

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 CPU
Equipped 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.

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.

SSD cache with Qtier™ optimization for around-the-clock acceleration
The TS-873 features SSD caching, and also supports optional M.2 SATA 6Gb/s SSDs (sold separately). Using an SSD cache boosts overall system performance, and is perfect for improving the overall workflow of random IOPS demanding applications such as virtualization. QNAP’s Qtier™ technology also continuously optimizes storage efficiency by tiering files and data across M.2 SSD, 2.5-inch SSD, and high-capacity SATA drives based on access frequency. The new Qtier™ 2.0 features IO-awareness that empowers SSD-tiered storage with a cache-like reserved space to handle burst I/O in real time, greatly maximizing the advantages of SSD.

Optimal computing power and 4K video playback with a graphics card
The TS-873 allows for installing a low-power graphics card (powered solely by the PCIe slot) to boost system performance. With a graphics card installed, the TS-873 also enables smoother video editing workflows and supports 4K UHD transcoding to deliver an exceptional multimedia experience. You can also use the QNAP remote control (sold separately) or the Qremote mobile app to use the NAS as a home theater PC.
