Who is the Synology RackStation RS2825RP+ best for?
A strong choice for
- Businesses consolidating file storage and backup in a rack environment
- Sites needing built-in 10GbE and network failover options
- Deployments requiring redundant power supplies
- Storage that may expand from 16 to 28 drive bays
- Teams using DSM for backup, synchronisation, collaboration or surveillance
Consider another model if you need
- You need a compact desktop NAS rather than a 3U rackmount system
- You do not have a compatible 4-post 19-inch rack
- You require more than 32 GB memory
- You need more than 28 total drive bays
- Your drive or expansion accessory is not listed as compatible
