Our verdict
Synology's four-bay for people who will actually use it: 2.5GbE, expansion to nine bays and M.2 NVMe caching (per the listing). It is a lot of money for a Home Assistant house; the real reasons to buy it are Surveillance Station, Docker workloads and large media libraries, not HA backups.
What can Home Assistant control on the Synology DS925+?
Home Assistant core has a first-party Synology DSM integration (local polling): drive health and temperature, CPU/memory/volume sensors, Surveillance Station cameras and a reboot/shutdown button, and it can store HA backups on the NAS. The docs cover DSM, not individual models, so this one is assumed to work rather than verified.
