Our verdict
Choose the UGREEN NASync DXP4800 Plus if its 10GbE connection, flexible drive sourcing and UGOS Pro workflow match a use case you have tested. Choose the Synology DS925+ if its DSM applications, backup administration and vendor-supported hardware ecosystem better fit your team. Both are four-bay appliances; neither is a complete backup strategy merely because it has RAID.
This is a documentation comparison, not a hands-on speed test. We have not validated either appliance's sustained throughput, restore time, support response or long-term reliability. Buy on a demonstrated workload and a tested recovery plan, not a vendor's peak transfer figure.
Hardware and compatibility
The UGREEN DXP4800 Plus specification lists four SATA bays, two M.2 slots, an Intel Pentium Gold 8505, 8 GB DDR5, one 10GbE port and one 2.5GbE port. Drives are sold separately. Its 10GbE port is useful only if the switch, client, cabling and disks can support the workload. Vendor transfer claims are not results from our testing.
The Synology DS925+ specification lists four drive bays, two M.2 slots, dual 2.5GbE ports, an AMD V1500B and 4 GB ECC memory. Check Synology's model-specific compatibility list for the exact drives you plan to buy. Compatibility and support conditions can change the real cost of a seemingly cheaper enclosure.
| Buying question | DXP4800 Plus | DS925+ |
|---|---|---|
| Network ports | 10GbE plus 2.5GbE | Two 2.5GbE ports |
| Included disks | None; quote disks separately | None; quote compatible disks separately |
| Operating system | UGOS Pro | DSM |
| Purchase risk to test | App maturity and your required backup workflow | Drive compatibility and your required expansion workflow |
A dual-port 2.5GbE configuration is not automatically a 5GbE single-client connection. Link aggregation and application behavior matter. Likewise, the UGREEN 10GbE port does not guarantee 10GbE file transfer through every storage configuration.
Price the complete system
Current storefront prices can change and may include short promotions. Request a US quote for the exact enclosure, four compatible drives of the needed size, any SSDs, network upgrades, UPS, offsite copy and support. Include an administrator's setup and quarterly restore-test time. Calculate usable capacity with your selected protection layout rather than summing raw disk labels. Leave room for version history and growth.
For a 10-person firm with modest files, either unit may be more hardware than necessary; a managed cloud backup service could be simpler. At 25 or 50 staff, concurrency, retention and restore targets matter more than headcount alone. Set a recovery-time objective and test a representative restore before choosing an enclosure.
Backup and security checklist
- Identify the data that actually needs recovery and its source system. A NAS can be a backup target, a primary file server, or both; do not count two folders on the same appliance as separate recovery copies.
- Pilot one workstation and one server or SaaS export with the selected software. Check scheduled backups, versioning and alert delivery.
- Keep another copy offsite or otherwise isolated from the appliance. Test recovery after simulating an unavailable NAS.
- Restrict admin accounts, require MFA where supported, apply updates and avoid direct internet exposure unless a documented remote-access design requires it.
- Record disk compatibility, support path, warranty, replacement time and who owns quarterly restores.
