QNAP TS-473A-8G - Network-attached storage server, Black

The QNAP TS-473A-8G is a 4-bay tower NAS designed for small and medium-sized businesses. It uses an AMD Ryzen Embedded V1500B quad-core 2.2 GHz processor to handle data-intensive tasks. The system includes 8 GB of DDR4 SO-DIMM memory, which can be expanded up to 64 GB across two slots. Network connectivity is provided by two 2.5 GbE RJ-45 ports supporting 100, 1000, and 2500 Mbit/s, which increase bandwidth and reduce congestion during multi-user access. Four hot-swap bays accommodate 3.5-inch and 2.5-inch SATA III HDDs or SSDs.

Two internal M.2 slots allow for SSD cache acceleration or storage pools without using the primary drive bays. The cooling system consists of one 120 mm fan and one 60 mm fan, with a rated noise level of 21.4 dB. The device runs on the QNAP Turbo System (QTS) and supports RAID 0, 1, 5, 6, 10, and JBOD. Security features include 256-bit AES encryption, FIPS 140-2 compliance, and support for secure protocols such as SSH and SSL/TLS. It is compatible with environments including Windows Server 2019, Windows 10, and macOS 10.10 Yosemite. Data protection is supported by integrated features including snapshots, iSCSI LUN backup, and cloud backup options.
