QNAP TS-4644.5
$566The TS-464 is the right answer if Plex transcoding is the primary use case. The Celeron N5095's iGPU handles four simultaneous 4K HEVC transcodes without choking, and the dual 2.5 GbE ports plus a PCIe slot for 10 GbE expansion give you more network headroom than the Synology DS923+. The trade-off is QTS — functional but less refined than DSM. Power users learn to live with it; casual users may not.
Strengths
- — Intel Celeron N5095 with iGPU — sustained 4K HEVC hardware transcoding for Plex/Jellyfin
- — Dual 2.5 GbE ports stock, port trunking gets close to 10 GbE speeds (~589 MB/s)
- — PCIe Gen 3 slot lets you add a 10 GbE card later
Watch-outs
- — QTS is less polished than Synology's DSM — more menus, less consistent UI
- — QNAP has shipped security vulnerabilities that received late patches in the past
- — Higher idle power than the Synology DS923+
