Powered by a 2.1 GHz AMD RX-421ND Quad-Core processor, which can be boosted up to 3.4 GHz, and 8GB of DDR4 RAM, which can be upgraded to 64GB, the TS-473 4-Bay NAS Enclosure from QNAP is a high-performance and energy efficient system that provides two PCIe 3.0 x4 slots that can accommodate M.2 SSD caching/10GbE connectivity, a wireless network card, and an entry-level graphics card to boost performance for 4K video performance. The TS-473 allows you to flexibly deploy a wide range of applications with a more affordable budget.
Network connectivity is achieved using four Gigabit Ethernet ports. When two 10GbE cards are installed in the PCIe slots and used simultaneously, read speeds are supported up to 2347 MB/s and write speeds can reach 1764 MB/s. When transferring data with 10GbE and volume encryption, read speeds max out at 2310 MB/s and write speeds go up to 1681 MB/s.
This 4-bay enclosure natively supports 3.5" SATA III hard drives, and 2.5" hard drives and SSDs are also supported using included 2.5" drive flat head screws. There are also two M.2 2260/2280 SATA III SSD slots. In order to enhance data transfers, SSD caching is supported on all four drive bays and both M.2 slots. Using the four 5 Gb/s USB 3.0 Type-A ports, this QNAP NAS can be connected to other devices, allowing you to easily transfer large media files and expand NAS storage. With a separately sold SAS PCIe expansion card and mini-SAS cable, this NAS can be expanded via two UX-800 or four REXP-1000 Pro expansion enclosures. Additionally, the TS-473 is validated with AES-NI and FIPS 140-2 AES 256-bit encryption, helping to prevent sensitive business data from unauthorized access and breaches.
QNAP has also engineered this NAS to also support RAID 0, 1, 5, 6, and 10, each of which offers data redundancy, performance, or a combination of both. For those who do not require a RAID, JBOD and single disk modes are also available. Included is a 250W AC adapter that runs using 100-240 VAC at 50/60 Hz, a power cord, two Ethernet cables, two M.2 heatsinks, two flat head screws for M.2 SSDs, and twelve flat head screws for 2.5" HDDs. Protection is provided by a limited 2-year warranty.
