The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Synology DS425+ earns its spot on the strength of media-server capability inside the polished DSM ecosystem. r/synology users specifically call it 'a superior machine for Plex' because its Intel chip includes a GPU that can handle hardware transcoding, contrasting it with AMD-based siblings that cannot. An untagged specialist review (nascompares.com) describes it as a competent 4-bay for users prioritizing software integration, low power and quiet 24/7 operation.
What reviewers liked
- Intel CPU with GPU transcoding singled out by r/synology as strong for Plex
- Synology DSM ecosystem praised for app polish, photo/backup tools and quiet 24/7 operation
- Untagged specialist review notes low power draw and reliable operation
Where it falls short
- Community and Plex forums flag tightened Synology-certified drive requirements
- Low verified-purchase volume (72 ratings) limits real-world signal
- Four-bay Synology costs more than comparably specced UGREEN units

Across the reviewers we read, the Synology DS425+ earns its spot on the strength of media-server capability inside the polished DSM ecosystem. r/synology users specifically call it 'a superior machine for Plex' because its Intel chip includes a GPU that can handle hardware transcoding, contrasting it with AMD-based siblings that cannot. An untagged specialist review (nascompares.com) describes it as a competent 4-bay for users prioritizing software integration, low power and quiet 24/7 operation.
The major caveat, raised across community threads and the Plex forums, is drive lock-in: Synology's newer Plus-series systems have tightened toward Synology-certified or first-party drives, which reviewers cite as a real downside versus UGREEN's open compatibility. Verified-purchase volume is also modest (72 ratings), so the real-world sample is thinner than the UGREEN units.
For buyers who value Synology's mobile apps, Photos and backup tooling and want a four-bay that can transcode media, the consensus is positive—just go in aware of the drive-compatibility trade-off.
