Synology DSM 7.3 — Automated Data Tiering, Security Boosts & Third‑Party Drive Support
Synology has unveiled DSM 7.3, focusing on easier management of growing data volumes and better protection of sensitive information. Key highlights include automated data tiering, enhanced security features, and policy changes around third‑party drive support.
What’s new
- Automated Data Tiering: DSM 7.3 can analyze file access patterns and migrate data between storage tiers (hot/warm/cold) automatically to optimize performance and storage costs.
- Security enhancements: Improvements include stronger local data protection and new masking/filtering options in the AI/management console to help safeguard sensitive information.
- Third‑party HDD support restored: Synology reversed prior restrictions for 2025+ NAS models, allowing non‑Synology 2.5″/3.5″ drives in storage pools again (note: some SSD/M.2 pools may still require HCL‑listed drives).
- Still restricted: Features such as automatic firmware updates and advanced telemetry may remain exclusive to Synology‑branded drives.
What this means for users
Automated tiering helps administrators reduce manual data shuffling and place frequently accessed files on faster media. Restoring third‑party HDD support improves flexibility and may reduce costs for users building or expanding NAS storage.
