Overview

The Synology DS223j is a 2-bay NAS designed for home users and small offices who want centralized, always-on storage without a steep learning curve or high price tag. Powered by a Realtek RTD1619B quad-core processor at 1.7 GHz and 1 GB of DDR4 RAM, it runs Synology's DiskStation Manager — a mature, browser-based operating system that handles everything from file sharing and photo management to automated backups and basic video surveillance. Setting it up is straightforward: install your choice of 3.5-inch or 2.5-inch SATA drives, connect the unit to your router via the 1GbE port, and follow the guided web setup.

Where the DS223j shines is in software. DSM gives you access to Synology Drive for private cloud syncing, Synology Photos for organizing and sharing images, and Hyper Backup for scheduled multi-version backups to external drives or remote servers. Two USB 3.2 Gen 1 ports on the back provide quick external drive connectivity. The trade-offs are hardware-related: the single Gigabit Ethernet port limits throughput, the 1 GB of soldered RAM cannot be expanded, and the ARM processor lacks the muscle for on-the-fly 4K transcoding. For straightforward file storage, backup, and light media duties, however, the DS223j delivers strong value at its price point.
