Synology DS923+ wins — We'd lean Synology for ease of setup and long-term software support
Scores: Synology DS923+ 7.4/10 · QNAP TS-464 7.2/10
We'd lean Synology for ease of setup and long-term software support. DSM is the most polished NAS OS available, Synology's app ecosystem is comprehensive, and the DS923+ is expandable to 9 bays with the DX517. The QNAP TS-464 wins if you want hardware video transcoding and plan to use the NAS as a media server with direct display output.
