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-673 6-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-673 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 2190 MB/s and write speeds can reach 1775 MB/s. When transferring data with 10GbE and volume encryption, read speeds max out at 2169 MB/s and write speeds go up to 1714 MB/s. This 6-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 six 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 expan model : ADATA XPG SX6000 Lite 512GB PCIe 3D NAND PCIe Internal Solid State Drive tag : NAS
