TS-873 - 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 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.
Note: Consult the QNAP Compatibility List before purchasing the graphics card. Graphics card will be supported in QTS 4.3.5 (or later) version.
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.
Note: USB 3.1 performance may vary depending on hardware/software limitations and usage environment.
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.
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.
Note: M.2 SSDs for NAS and QM2 cards are sold separately.
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.
Note: The M.2 SSD is optional. As M.2 SSD operations can easily generate excessive heat, it is recommended to install a heatsink (from QNAP or a third-party provider) on the M.2 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.
Note:
1. Supported video formats depend on the hardware and software specifications of the devices. Playback capability and quality may vary due to factors including the original file formats/quality, hardware and software limitations, and output devices.
2. Consult the QNAP Compatibility List before purchasing the graphics card.
3. Graphics card will be supported in QTS 4.3.5 (or later) version.
Use your NAS as a wireless base station
Install a compatible PCIe wireless network card (for example: QNAP QWA-AC2600) on the TS-873 and use with the WirelessAP Station app to use your NAS as a convenient wireless base station. Your mobile devices and PCs can directly connect to your NAS for easy access to its services and Internet connection.
Upgrade your IT environment with QNAP's fast and affordable 10GbE Switch!
QNAP 10GbE/NBASE-T unmanaged switches allow you to instantly upgrade your network environment at a cost-effective price. With a 10GbE network you can enjoy blazing-fast transfer speeds, empower bandwidth-demanding tasks like virtualization, and enable simultaneous real-time access to large NAS-based files using multiple workstations (ideal for video editing and multimedia). QNAP also provide a 10GbE PCIe network expansion card for the TS-873 and Windows/Linux PCs to take advantage of high-speed LAN environments.

Coupled with Qsync - a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization - any file uploaded to the TS-873 will be made available for all linked devices, such as computers, laptops and mobile devices. You can sync shared folders and team folders for group file sharing, greatly enhancing the flexibility of team projects and collaboration. Files can be centrally managed using File Station, including files from mobile devices and optical disc drives. File Station also allows you to mount a remote NAS, and transfer files between your NAS and public cloud services for greater convenience.
NAS as a Multi-OS Platform
Virtualization Station and Container Station provide comprehensive solutions for creating virtualized environments to improve business IT infrastructure, workflows, and productivity.
Virtualization Station allows you to run multiple Windows, Linux, UNIX and Android virtual machines on the TS-873. You can use Virtual Network Computing (VNC) through a browser to manage the VMs. Virtualization Station is ideal for organizations to run multiple applications on a single NAS.
Container Station integrates LXC and Docker lightweight virtualization technologies. You can download apps from the built-in Docker Hub to easily import/export container apps and manage access control, enjoying the benefit of easy installation, transferability and high-efficiency.
