TS-473A-8G
AMD Ryzen™ V1500B quad-core/ 8 threads 2.2 GHz processor, 8 GB RAM (1 x 8 GB)
High performance AMD Ryzen™ processor
The TS-473A 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-473A 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.

Switch operating systems for optimal data integrity and reliability
The TS-473A also supports QuTS hero - QNAP’s ZFS-based NAS operating system. Providing end-to-end data integrity, data reduction (inline data deduplication, compression and compaction), and much more, QuTS hero uses additional system resources to ensure an optimal environment for protecting business data.
Note:
1. QTS and QuTS hero use different file systems. You must remove all the drives from the TS-473A before switching from QTS to QuTS hero.
2. QuTS hero requires a NAS with at least 8 GB memory.
3. Inline Data Deduplication requires a NAS with at least 16 GB memory (at least 32 GB memory is recommended for optimal performance).
4. It is recommended to create an SSD RAID with at least two SSDs for the QuTS hero system drive to attain optimal system performance. Please note that M.2 SSD hot-swapping is only supported by M.2 SSD slots on PCIe cards (such as the QM2). M.2 SSD slots that are built into the NAS do not support hot-swapping.

Obtain performance benefits from M.2 SSD caching
The TS-473A 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-473A 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.
Note: Qtier Technology is supported by QTS

Upgrade to 10GbE and abundant capability with PCIe expansion
The TS-473A features two PCIe Gen 3 x4 slots that allows for various expansion cards for expanding application potential.
Note: TS-473A uses low-profile expansion cards
5GbE/10GbE network card
Enable lightning-fast throughput for bandwidth-demanding tasks, such as virtualization, massive data transmission, and fast backup/restoration.
QM2 M.2 SSD/10GBE CARD
Adds M.2 NVMe SSD/ SATA SSD caching or 10GbE (10GBASE-T) connectivity to the NAS for optimized performance and bandwidth.
USB 3.2 GEN 2 (10GBPS) expansion card
