Synology DS124 1-bay
Score: 62/100
Synology DS223j 2-bay
Score: 70/100Rankings

The DS223j is a compact, diskless two-bay NAS that delivers the full DSM experience, RAID 1 redundancy and low power draw. It's ideal for basic file storage and backup, though its single-gigabit port and limited RAM keep it from handling demanding media tasks.
The DS124 is a compact single-bay NAS that runs DSM, offers Btrfs support and low power consumption, targeting home users and small offices needing reliable file storage. Its simplicity comes at the cost of limited RAM, no RAID and no media transcoding capabilities.

“This NAS is easy to set up, like all Synology products, and the system does what you expect. I'm using it as an SMB drive with automatic backup to Synology C3, and that works like a charm. You could run other services, but I'd rather have a separate device with more RAM and a better CPU for that.”
