Ranked #20 in NAS Devices

169 LP on the category ladder what's LP?

The worst value on the board: more money than the DS223j for almost nothing, in a brand whose mid-range case XDA and How-To Geek both argue has collapsed. Save with the DS223j or stretch to the DS225+.

Flagged as a product to avoid

2 of 5 research runs entered this as a product to avoid rather than a pick.

The worst value in the bracket: it costs more than the DS223j for hardware that barely improves on it, and it lacks the Plus-tier software headroom that justifies the DS225+, in a brand whose mid-range value case XDA and How-To Geek both argue has collapsed.

It sits in the same slot as the DS224+ with a weaker processor and slower networking, so buyers pay the Synology software premium for last-generation hardware; the DS224+ is the one to buy instead.

A few reviews mention the DS223's transcoding limitations for Plex 4K, which is a real limitation but also a case of buying the wrong tool for the job. The DS223 is not a transcoding machine.
