About this comparison
Synology DS925+ and UGREEN DXP4800 Plus compared by drive layout, network and processor, best use.
The practical choice turns on network and processor and best use, then on the constraints in your own setup.
Before you choose
How they fit your plans
A recovery schedule should name how far back you can go
For one shared folder, a plan to retain every hourly snapshot for ten days needs 240 recovery points. That fits DS925+’s documented 256-per-folder ceiling, provided storage capacity and the rest of the configuration allow it. Choose Synology when this verified retention arrangement is central to the purchase. Do not assume a faster DXP4800 Plus Ethernet port supplies the same recovery policy without checking its exact software.
Facts behind this advice
Ten days multiplied by 24 hourly points is 240. This is a retention-count check, not a space estimate or a claim that local snapshots replace an independent backup.
A four-terabyte overnight copy can rule out a single 2.5GbE path
If the required backup is 4TB within two hours over one Ethernet link, DS925+ cannot meet the window even at its 2.5Gbps line rate. DXP4800 Plus has the appropriate faster port to investigate, but the source, destination disks and switch must sustain the job. Choose Synology if incremental backups or a longer window reduce that requirement. Choose UGREEN only after validating the complete faster route.
Facts behind this advice
Decimal 4TB multiplied by eight and divided by 7200 seconds requires about 4.44Gbps before overhead. Dual ports are not automatically one faster connection. This calculation supplies a lower bound, never a measured completion time.
Winner by situation
Start with what you need it to do
Protect family photos
For network and processor, Synology DiskStation DS925+ records “2.5 Gbps network. Best treated as file storage” and UGREEN NASync DXP4800 Plus records “10 Gbps network. Plex use supported”. This affects connection compatibility and available data paths. A higher label does not guarantee the same real-world result in every setup.

What you give up
Every choice has a cost
If you choose Synology DiskStation DS925+
- Expansion adds bays but not 10GbE.
If you choose UGREEN NASync DXP4800 Plus
- The chassis cannot expand past four SATA bays.
What matters in practice
How to make the call
The useful difference
Both start with four SATA bays and two M.2 slots.
What the numbers change
DS925+ can reach nine bays with expansion.
The trade-off
DXP4800 Plus includes 10GbE and 2.5GbE.
What this comparison cannot tell you
- Drive compatibility changes over time.
- Real transfer speed depends on the full network and drive array.
- Plex behavior depends on the exact media format and client.
