Main trade-off
Synology DiskStation DS425+
The fastest native port is 2.5GbE.
Head-to-head
Synology DiskStation DS425+ vs UGREEN NASync DXP4800 Plus: UGREEN clears a 6GB RAM limit and includes 10GbE
The short answer
Choose DS425+ when keeping a DSM-based photo, backup or surveillance workflow is the priority. Choose DXP4800 Plus when native 10GbE or more than 6GB of supported memory is a firm requirement.
Before you choose
The reasoning and the trade-offs
The native network ceiling differs by four times
UGREEN's fastest port is rated four times higher, but that does not promise four times faster file transfers. A 2.5GbE client still prevents the route from using 10GbE.
What this is based on
10 / 2.5 = 4 for nominal link rates. The disk array, protocol, client and switch can each limit throughput.
Main trade-off
UGREEN NASync DXP4800 Plus
A DSM-based workflow requires migration and feature checks.

About this comparison
Compare DS425+ and DXP4800 Plus for a four-drive NAS, weighing an existing DSM workflow against native 10GbE and more room for memory-heavy services.
Choose DS425+ when keeping a DSM-based photo, backup or surveillance workflow is the priority. Choose DXP4800 Plus when native 10GbE or more than 6GB of supported memory is a firm requirement.
Winner by situation
Start with what you need it to do
My family backup and photo workflow already uses DSM
DS425+ retains that software environment. Verify the exact migration and application support.
- Synology DiskStation DS425+
- Better fit
- UGREEN NASync DXP4800 Plus
- Depends
A native 10GbE port is mandatory
DXP4800 Plus includes 10GbE. DS425+ tops out at 2.5GbE on its native ports.
- Synology DiskStation DS425+
- Not suitable
- UGREEN NASync DXP4800 Plus
- Better fit
My planned services need more than 6GB RAM
UGREEN's 64GB official ceiling leaves more capacity. Check the actual application allocation and compatible modules.
- Synology DiskStation DS425+
- Not suitable
- UGREEN NASync DXP4800 Plus
- Better fit
I need four hard-drive bays for shared storage
Both satisfy the bay count. The OS workflow and the rest of the network decide the useful difference.

What matters in practice
The differences that matter
The native network ceiling differs by four times
UGREEN's fastest port is rated four times higher, but that does not promise four times faster file transfers. A 2.5GbE client still prevents the route from using 10GbE.
How we reached this conclusion
10 / 2.5 = 4 for nominal link rates. The disk array, protocol, client and switch can each limit throughput.
An 8GB memory requirement already exceeds DS425+
If a supported application plan genuinely requires 8GB total, it is outside Synology's 6GB official maximum. UGREEN supplies 8GB before an upgrade.
How we reached this conclusion
8GB - 6GB = 2GB above Synology's ceiling. UGREEN's included 8GB matches the stated target, before any extra overhead.
Four drive bays do not require accepting a new software platform
Both offer four SATA bays and two M.2 slots. A DSM user choosing UGREEN for extra CPU or network capacity is also choosing a software migration.
How we reached this conclusion
Equal physical counts: four SATA bays and two M.2 slots. DSM and UGOS Pro are distinct systems. Application portability must be checked separately.

Meaningful differences
What changes the fit
| What changes | Synology DiskStation DS425+ | UGREEN NASync DXP4800 Plus | Why it matters |
|---|---|---|---|
| Native network connections | One 2.5GbE plus one 1GbE | One 10GbE plus one 2.5GbE | UGREEN fits a native 10GbE plan. Synology's fastest native port is 2.5GbE. |
| Included memory | 2GB DDR4 | 8GB DDR5 | UGREEN begins with 6GB more memory. This is a capacity difference, not a measured responsiveness result. |
| Official maximum memory | 6GB | 64GB | Memory-heavy services may exceed Synology's documented ceiling before all four disk bays are used. |
| Processor | Celeron J4125, 4 cores and 4 threads | Pentium Gold 8505, 5 cores and 6 threads | Check each application's support and requirements. A core count is not a workload benchmark. |
| Management platform | Synology DSM | UGOS Pro | The platforms have separate apps and configuration paths. Hardware specifications do not establish feature-by-feature software equivalence. |
What you give up
Every choice has a cost
If you choose Synology DiskStation DS425+
- The official memory ceiling is 6GB.
If you choose UGREEN NASync DXP4800 Plus
- Its 10GbE port needs matching network equipment to be useful.
Recommendation switch
The decision flips if...
Keeping your existing DSM workflow is the deciding requirement
Choose Synology DiskStation DS425+. DS425+ stays within the Synology software environment.
You require native 10GbE or more than 6GB supported RAM
Choose UGREEN NASync DXP4800 Plus. DXP4800 Plus supplies a 10GbE port and a 64GB memory ceiling.
You need more than four SATA bays
Choose neither. Both enclosures provide four SATA bays.
What matters in practice
How to make the call
Begin with the applications you cannot replace
A familiar DSM workflow is a concrete reason to choose Synology. List the exact backup, photo and surveillance functions you use and confirm them for DS425+. Do the same for UGOS Pro before assuming that similar app names provide an identical workflow.
Use network speed only when the rest of the route supports it
UGREEN's built-in 10GbE port is a substantial connection difference. It does not improve a 1GbE computer's link by itself, and it does not establish that a hard-drive array can sustain the wire rate. Budget adapters and switching where required.
Treat memory and drive compatibility as purchase checks
DS425+ has a much smaller supported memory range. That may be sufficient for your actual jobs, but it is a hard boundary for a larger allocation. Check the current drive compatibility lists on both platforms rather than relying on old claims about accepted drive brands.
What this comparison cannot tell you
- No workload, software-usability or reliability testing was performed. Manufacturer memory and port specifications do not prove application performance.
