Synology has reversed its policy of banning third-party hard drives from its NAS devices, allowing users to once again use drives from other manufacturers without restrictions. This decision comes after a backlash from customers and a decline in sales. The change is part of the release of DSM 7.3, which restores the flexibility that made Synology popular in the first place. Users can now choose from a wider range of drives, including those from Seagate, WD, and others.
