High Performance AMD Ryzen™ Processor

The TS-873A is powered by an AMD Ryzen™ V1000 series V1500 quad-core 2.2 GHz processor with up to 64GB RAM (ECC memory is supported*) and features USB 3.2 Gen 2 ports for speeds up to 10 Gb/s. The TS-873A also provides one USB Type-C port for supporting more devices to transfer large media files across devices, providing you with a more efficient workflow.

* Using ECC memory requires the removal of pre-installed memory, as you cannot use non-ECC memory with ECC memory.

Transform Your Network with a Wallet-friendly 2.5GbE Switch

Upgrading your network shouldn't break the bank, and 2.5GbE connectivity provides immediately noticeable improvements compared to standard 1GbE. QNAP offers 2.5GbE switches that supports Multi-Gigabit NBASE-T™ and allows you to use existing CAT5e cables to connect multiple computers and NAS, assisting organizations in implementing high-speed, secure and scalable network environments without going over budget.

Obtain Performance Benefits from M.2 SSD Caching

The TS-873A features 2 M.2 NVMe SSD slots for you to enjoy SSD caching or Qtier auto tiering Technology.

Improve random data access speeds with an SSD cache - SSD caches accelerate IOPS performance and reduce latency for storage volumes. They are perfect for IOPS-demanding applications (including databases and virtualization) and can significantly improve overall workflows.

Maximize the value of SSDs with Qtier Technology - Qtier™ Technology empowers the TS-873A with auto tiering that helps continuously optimize storage efficiency by automatically moving data between M.2 SSDs, 2.5-inch SSDs, and high-capacity HDDs based on the data's access frequency. 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 SSDs.

Upgrade to 10GbE and Abundant Capability with PCIe Expansion

The TS-873A features two PCIe Gen 3 x4 slots that allows for various expansion cards for expanding application potential.

Note: TS-873A uses high-profile expansion cards.

Easy and Secure File Management

File Station allows direct management of files stored on the TS-873A and in the cloud. Users can easily upload files from their PC, drag/drop files between folders, rename/delete files, and configure file/folder permissions to prevent unauthorized access. Microsoft Office Online can also be used to directly view/edit Microsoft Office documents stored on the TS-873A. Confidential/sensitive data can be encrypted to add extra security.

Install a Graphics Card for GPU-accelerated Computing

Graphics cards are optimized for graphical calculations and transformations, but require significantly more power than other hardware. The TS-873A features PCIe slots to support high-profile graphics cards that do not need power cables, including NVIDIA® GeForce® GTX1650 graphics cards to boost performance of applications such as video editing , 4K UHD transcoding, imaging processing in QTS and performance of virtual machines via GPU passthrough.

Build an Affordable Fibre Channel SAN Environment

Common Fibre Channel Storage Area Networks (SAN) devices are often costly. By installing a QNAP 16Gb Fibre Channel card (QXP-16G2FC 16Gb) in the TS-873A, you can set a Fibre Channel Target using the iSCSI & Fibre Channel app. Moreover, the LUN Masking and Port Binding features provide an additional layer of data security.
