QNAP TS-473A - NAS server - 4 bays - SATA 6Gb/s - RAID JBOD, RAID 0, 1, 10, 5, 6 - RAM 8 GB - 2.5 Gigabit Ethernet - iSCSI support - with QSW-1105-5T switch

AMD Ryzen quad-core 2.2 GHz 2.5 GbE NAS supports M.2 NVMe SSD and PCIe expansion for adding 10 GbE high-speed connectivity and M.2 SSD; QTS and QuTS hero dual operating system for greater flexibility.

• Both 2.5 GbE ports are backwards compatible with 1 GbE / 100 MbE speeds
• Add extra functionality with PCIe cards, including 10 GbE ports, SSD caching, extra USB 3.2 Gen 2 ports, wireless networking, or Fibre Channel
• Supports NVIDIA graphics cards for video processing or GPU-passthrough to VMs
• Features two M.2 PCIe NVMe SSD slots for Qtier technology and SSD caching
• Host containerized applications and virtual machines with various operating systems
• Features QTS operating system and supports switching to ZFS-based QuTS hero for greater reliability

• 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.
• 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.
• PCIe expansion
  The TS-473A features two PCIe Gen 3 x4 slots that allow for various expansion cards for expanding application potential.
