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.
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.
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.
