The QNAP TS-453D is a 4-bay NAS that is designed to take advantage of faster speeds from 2.5GbE connections and extend those benefits to the devices connected to it. QNAP has made several changes recently to push the networking speeds form 1GbE to 2.5GbE connections through NAS, switches, and AICs. The TS-453D is yet another device that will help users past the networking bottleneck to faster connectivity speeds.
