Synology DiskStation DS225+ review

Synology DiskStation DS225+ is the pick for buyers who care most about software. Synology's DSM ties together file sync across devices, automatic photo backup, versioning to roll back deleted files, site-to-site sync and sync with over 20 cloud providers such as AWS S3, Backblaze B2, Dropbox, Google Drive and Microsoft OneDrive. Surveillance Station manages up to 25 IP cameras on this model. The hardware is more modest: an Intel Celeron J4125 quad-core CPU, 2 GB of DDR4 RAM expandable to 6 GB, one 2.5GbE and one 1GbE port, and up to 40 TB of raw storage with 20 TB drives. Synology quotes over 282/217 MB/s sequential read and write. The standard hardware warranty is three years, one more than UGREEN and TerraMaster. Synology does not sell it directly on its US page, so the price check is pending. We compared documented features and published prices; we did not test the NAS ourselves.
