QNAP TS-473-4G-US Specifications

    Qnap NAS TS-473-4G-Us 4-Bay AMD RX-421ND 4GB DDR4 4x 2.5 3.5 4XGBE LAN


    Rear View

    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-473 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-473 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-473 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-473 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-473 enables lightning-fast multi-tasking with low power consumption for up to 2347 MB/s throughput with a 10GbE configuration. With a hardware- accelerated AES-NI encryption engine, the TS-473 also provides unmatched encryption performance in its class (up to 2310 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-473 can fulfill diverse application needs.

    SSD caching and 10GbE connectivity

    The TS-473 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.
