The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
The Synology DS925+ is the most controversial unit in this roundup, and the reviewers we read do not pretend otherwise. dongknows.com calls it "a solid server stunted by the lack of a 10GbE upgrade option, available in previous model." neowin.net frames its review explicitly around Synology "backtracking on locking out unapproved drives." An Android Central headline surfaced in r/synology summarizes the mood: "much-needed upgrades, but Synology's hard drive restrictions make it hard to recommend." blackvoid.club is more positive, noting the unit "performs admirably even without a 10GbE option" over SMB. The community split is real.
What reviewers liked
- DSM remains the most polished NAS OS per r/synology consensus
- blackvoid.club confirms strong SMB throughput in real-world use
- Intel CPU with integrated graphics enables hardware transcoding
- Mature backup, snapshot, and replication tooling
- Wide third-party app ecosystem and long-term firmware support track record
Where it falls short
- dongknows.com explicitly criticizes the loss of the 10GbE upgrade option vs. the previous-gen model
- Drive-compatibility restrictions are the dominant complaint in r/synology threads
- 4.0/5 Amazon rating is lowest among our top five picks
- Hardware is modest for the price compared to UGREEN's N100/Pentium Gold offerings
- neowin.net frames the unit primarily in the context of Synology walking back drive lockouts - a trust hit reviewers haven't forgotten
The Synology DS925+ is the most controversial unit in this roundup, and the reviewers we read do not pretend otherwise. dongknows.com calls it "a solid server stunted by the lack of a 10GbE upgrade option, available in previous model." neowin.net frames its review explicitly around Synology "backtracking on locking out unapproved drives."

The community split is real. r/synology threads contain both "first-NAS buyers happy with their setup" posts and longtime Synology users frustrated that the previous-gen DS923+ had a 10GbE expansion path the DS925+ removed. Verified-purchase Amazon reviewers land at 4.0/5 across 104 reviews - the lowest in our top five, which reviewers attribute to the drive policy debate rather than any hardware defect. For buyers who specifically want a 4-bay Synology and value DSM, it is still the natural pick; for buyers who want maximum hardware-per-dollar in 4 bays, the UGREEN DXP4800 Plus is the more frequent community recommendation.
- Supports drives on the model's official compatibility list
- Up to 522/565 MB/s sequential read/write throughput supports stable data transfers.
- Dual 2.5GbE ports provide fast network transfer speeds and increased redundancy.
- Leverage built-in file and photo management, data protection, virtualization, and surveillance solutions.
- Backed by Synology's 3-year limited hardware warranty.
