Overview

• DSM 7.3 removes the 2025 drive lock, restoring full support for third-party HDDs and 2.5-inch SATA SSDs with health monitoring and alerts.
• Drives from brands such as WD Red and Seagate IronWolf now work on models including the DS925+, DS1825+, and DS425+ without warnings or reduced features.
• Synology says 2025 Plus, Value, and J series running DSM 7.3 will allow installation and storage‑pool creation with non‑Synology drives.
• M.2 slots remain restricted to Synology SSDs for creating storage pools on 2025 units.
• Reviewers and users had condemned the policy, and reports indicate the reversal follows a sales slump; DSM 7.3 also delivers updates to Synology Drive, MailPlus moderation, and security.
