The catch

The 1GB of RAM is soldered to the board and cannot be upgraded, permanently limiting this device to only the most basic file-serving and backup tasks.

Spec, translated

The 'Secure private cloud' marketing means this is a network-attached storage (NAS) box that runs Synology's well-regarded operating system, letting you build a personal file and backup server in your home.

Lab notes

The observations that actually change the buying decision.

The 1GB of non-upgradeable RAM is the primary performance bottleneck. It's sufficient for basic file serving but will struggle with multiple apps or users.

The Realtek RTD1619B CPU is power-efficient but lacks hardware transcoding capabilities, making it a poor choice for running a Plex server that needs to convert video.

A single 1GbE network port physically limits file transfers to a maximum of ~115 MB/s, which is adequate for backups but slow for heavy, direct file-editing workflows.

As a 2-bay unit configured for data protection (RAID 1), your usable storage capacity is equal to only one of the drives you install.

Why you should buy

This is for a user whose primary need is a low-cost, set-and-forget backup destination for household computers. It also serves as a basic private replacement for cloud photo and file services for those who can tolerate a slow interface.

Why you should skip

Anyone planning to run a media server with video transcoding (like Plex), serve files to several active users, or experiment with Docker containers should invest in a 'Plus' series model. The anemic, fixed 1GB of RAM is a hard ceiling on this unit's capability.
