"World-class software on intentionally limited hardware for basic home backup and file serving."
The promise of a 'Professional File Collaboration' hub is constrained by entry-level hardware. It works well for sharing documents and photos, but simultaneous access by a team or handling large media files will saturate its processor and 1GbE network connection.
This is a solid choice for a user's first NAS, primarily for automated computer backups and creating a personal photo cloud. It's a set-and-forget appliance for those who prioritize Synology's polished software over raw hardware performance.
Anyone wanting to run a performant Plex media server with 4K transcoding should look elsewhere. Power users who want to run virtual machines or many Docker containers will find the 2GB of non-upgradeable RAM immediately insufficient. Users with a multi-gigabit home network will be leaving speed on the table.
