Main trade-off
TerraMaster F4-425 Plus N150 16GB
The fastest included port is 5GbE, so a 10GbE client link cannot negotiate 10GbE to this chassis.
Head-to-head
TerraMaster F4-425 Plus N150 16GB vs UGREEN NASync DXP4800 Plus: More supplied RAM or native 10GbE for an equipped workstation
The short answer
The F4-425 Plus gives three M.2 slots and 16GB memory as supplied. The DXP4800 Plus fits a workstation that already has a 10GbE connection.
Before you choose
The reasoning and the trade-offs
Protected capacity with equal 12TB drives
F4-425 Plus N150 16GB gives 36TB and UGREEN NASync DXP4800 Plus gives 36TB before formatting in this example. Changing chassis does not increase this protected capacity.
What this is based on
Assume every SATA bay contains a supported 12TB disk. Two-bay RAID 1 uses one disk of usable capacity. For three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. This is an illustrative layout, not included storage or a backup.
Main trade-off
UGREEN NASync DXP4800 Plus
UGOS Pro has a younger app catalog than Synology DSM.

About this comparison
Compare F4-425 Plus N150 16GB and DXP4800 Plus by protected storage, included networking and the exact SSD or application layout you need.
A 5GbE hybrid pool and a 10GbE editing link lead to different choices.
Winner by situation
Start with what you need it to do
A protected archive using 12 TB disks in every internal SATA bay
Using RAID 1 for two disks or RAID 5 for three or more disks, F4-425 Plus N150 16GB gives 36TB and UGREEN NASync DXP4800 Plus gives 36TB before formatting in this example. Changing chassis does not increase this protected capacity.

Several local services sharing the supplied RAM
TerraMaster F4-425 Plus N150 16GB supplies 16 GB RAM and supports 32 GB. UGREEN NASync DXP4800 Plus supplies 8 GB and supports 64 GB. Compare the stated application memory requirement with the supplied configuration before budgeting for an upgrade. RAM capacity alone does not establish application speed.

What matters in practice
The differences that matter
Protected capacity with equal 12TB drives
F4-425 Plus N150 16GB gives 36TB and UGREEN NASync DXP4800 Plus gives 36TB before formatting in this example. Changing chassis does not increase this protected capacity.
How we reached this conclusion
Assume every SATA bay contains a supported 12TB disk. Two-bay RAID 1 uses one disk of usable capacity. For three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. This is an illustrative layout, not included storage or a backup.
100GB transfer at the included port ceiling
The line-rate lower bound is 160 seconds for F4-425 Plus N150 16GB and 80 seconds for UGREEN NASync DXP4800 Plus. Real copies take longer. A 1GbE client makes the lower bound 800 seconds for both.
How we reached this conclusion
Decimal 100GB × 8 = 800 gigabits. Divide 800 by the fastest included port rate, 5Gbps or 10Gbps. Ignore protocol overhead only for this lower-bound calculation. Optional adapters and aggregated ports are excluded.
The larger memory ceiling belongs to the UGREEN
The F4-425 Plus supplies 8GB more RAM, but the DXP4800 Plus supports 32GB more at its documented maximum. Choose the supplied budget for an immediate deployment and the ceiling for a workload with a specific growth forecast.
How we reached this conclusion
Supplied RAM: 16 minus 8 = 8GB in TerraMaster favor. Supported ceiling: 64 minus 32 = 32GB in UGREEN favor. These are capacity limits, not processing-speed measurements.

Meaningful differences
What changes the fit
| What changes | TerraMaster F4-425 Plus N150 16GB | UGREEN NASync DXP4800 Plus | Why it matters |
|---|---|---|---|
| Fastest included Ethernet port | 5GbE | 10GbE | The client, switch and storage must keep up before this port rate helps a transfer. |
| Supplied RAM | 16GB | 8GB | This is the installed memory budget before purchasing upgrade modules. |
| Supported RAM ceiling | 32GB | 64GB | This sets the manufacturer-supported upgrade ceiling for concurrent services. |
| M.2 storage slots | 3 | 2 | Plan SSD cache and storage pools separately from the SATA archive. |
| Processor | Intel N150 | Intel Pentium Gold 8505 | Media engines, application architecture and concurrency depend on this platform. |
| Software and expansion route | TOS | UGOS Pro | Choose the applications and supported add-ons required for the job. |
What you give up
Every choice has a cost
If you choose TerraMaster F4-425 Plus N150 16GB
- This record is the N150 16GB listing. The N95 and other memory variants need separate checks. Drives are sold separately.
If you choose UGREEN NASync DXP4800 Plus
- The chassis cannot expand past four SATA bays.
Recommendation switch
The decision flips if...
You want 16GB RAM and three M.2 slots as supplied
Choose TerraMaster F4-425 Plus N150 16GB. F4-425 Plus supplies 16 GB RAM and three M.2 slots. DXP4800 Plus supplies 8 GB and two M.2 slots, although its later memory ceiling is higher.
Your workstation already uses 10GbE
Choose UGREEN NASync DXP4800 Plus. DXP4800 Plus includes a 10 GbE port, compared with 5 GbE on F4-425 Plus. A compatible workstation, switch and storage workload are still needed to use the faster link.
What matters in practice
How to make the call
Start with the required storage layout
The F4-425 Plus gives three M.2 slots and 16GB memory as supplied. The DXP4800 Plus fits a workstation that already has a 10GbE connection.
Work through the drive budget
For four equal SATA disks, protected capacity is unchanged. On both models the fast network can outrun a slow disk workload, so specify the SSD pool or array before budgeting for Ethernet adapters.
Check the actual client and application plan
The DXP4800 Plus officially supports 64GB memory compared with 32GB on the F4-425 Plus. The latter begins with more RAM, so compare the supplied configuration and the planned upgraded configuration separately.
What this comparison cannot tell you
- Capacity examples use equal 12TB drives before formatting, snapshots and filesystem overhead.
- Ethernet calculations are lower bounds. Disk performance, network protocol and other traffic add time.
- Memory capacity does not certify application speed or a VM count.
