Tested by TechRadar
Consistently praised
- Quiet operation and robust, tool-less build (drives in under 5 minutes)
- Vast, mostly-free business and smart-home app library with included multi-user licenses
- Two integrated 2.5GbE ports and fast setup (under 15 minutes)
Commonly flagged
- No PCIe slot means no 10GbE upgrade path, capping peak transfer speed
- Third-party drive compatibility more limited than ever; costly Synology-only drives
- New USB-C port is only for drive-bay expansion (eSATA removed)
Where reviewers disagree Single-source, so no cross-outlet comparison is possible. TechRadar itself notes that bonding the two 2.5GbE ports actually reduced single-client throughput (down to 168 MB/s) rather than boosting it, so the dual-LAN benefit is situational (many simultaneous streams, not raw single-connection speed).
The sources (1)
Volume-to-volume sustained transfer (peak): 435 MB/s · Single 2.5GbE wired transfer, HDD volume: 280 MB/s · Single 2.5GbE wired transfer, NVMe volume: 282 MB/s · Bonded dual-2.5GbE (5Gbps) single-client transfer: 168 MB/s · Wi-Fi 7 (6GHz) transfer, SSD volume: 278 MB/s
As an all-around package, it's the best on the market for its target audience.
What's most bothersome, though, is the lack of a PCIe network expansion for upgrading to 10GbE connectivity, which limits the possible network transfer speeds.
Finally, it's worth noting that compatibility with third-party drives is now strictly limited.
