Synology DS223 vs Synology DS225+

The Synology DS225+ wins overall, with an Intel processor that supports Docker and virtual machines, hardware transcoding, a 2.5 GbE port and a longer warranty. The Synology DS223 costs less and runs noticeably quieter.

The processor. The Synology DS223 uses a Realtek ARM chip that can't run Docker, virtual machines or hardware transcoding, while the Synology DS225+ uses an Intel Celeron that supports all three, plus a 2.5 GbE network port the DS223 doesn't have.

No. Its ARM processor doesn't support Container Manager or Virtual Machine Manager. The Synology DS225+ can run both, so it's the model to pick for self-hosting.

The Synology DS223 is the quieter of the two, at 14.6 dB(A) against the Synology DS225+'s 19.6 dB(A), worth weighing if the unit will sit somewhere you sleep or spend quiet time.

Buyers who want to run Docker containers, host Home Assistant, transcode Plex libraries in hardware, or use the faster 2.5 GbE port.

Buyers who want simple, reliable two-bay file storage, backup and media serving without Docker or virtual machines, and who value a quieter enclosure and a lower price over expandability.
