The QNAP TVS-873 looks a little different from most other NAS products at first glance, and the internal components are quite surprising too. This NAS features a powerful quad-core AMD CPU and an integrated R7 GPU ? both beyond the demands of what you would expect from a file-server NAS. As you may have guessed, TVS-873 isn't designed to function as a simple ?network attached storage? device. We?ve used this NAS as a fully-fledged all round server for a month, running several Virtual Machines, a file server, docker containers, Plex media server and several other smaller services. If you?ve not used a high-end NAS, it's time to re-think what they can do.
