Synology Restores Third-Party HDD and SATA SSD Support on 2025 DiskStations With DSM 7.3

Synology frames the change as temporary flexibility pending broader certification with drive manufacturers.

Overview

  • DSM 7.3 enables installation and storage‑pool creation with non‑validated 3.5-inch hard drives and 2.5-inch SATA SSDs on 2025 Plus, Value, and J-series DiskStations.
  • M.2 drives still require listings on Synology’s hardware compatibility list to create storage pools or cache.
  • The move rolls back a 2025 policy that curtailed core features for third‑party disks, including storage pools, health monitoring, deduplication, and firmware updates.
  • Reports cited falling sales and strong community backlash against the verified‑drive requirement, which rivals highlighted as they promoted more open alternatives.
  • The affected 2025 lineup includes DS225+, DS725+, DS425+, DS925+, DS1525+, and DS1825+, and earlier NAS generations were not subject to this specific restriction.
