Head-to-head
TerraMaster F4-425 vs UGREEN NASync DXP2800: Four-disk RAID archive or two hard drives plus SSD apps
The short answer
The F4-425 makes room for four SATA disks and RAID 5. The DXP2800 uses two SATA bays but adds two M.2 slots and 8GB memory for a compact application server.
Before you choose
The reasoning and the trade-offs
Protected capacity with equal 12TB drives
F4-425 gives 36TB and UGREEN NASync DXP2800 gives 12TB before formatting in this example. The difference is 24TB before filesystem overhead.
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 DXP2800
Two SATA bays cap growth and rule out parity layouts.

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 gives 36TB and UGREEN NASync DXP2800 gives 12TB before formatting in this example. The difference is 24TB before filesystem overhead.

Several local services sharing the supplied RAM
TerraMaster F4-425 supplies 4 GB RAM and supports 16 GB. UGREEN NASync DXP2800 supplies 8 GB and supports 16 GB. Compare the stated application memory requirement with the supplied configuration before budgeting for an upgrade. RAM capacity alone does not establish application speed.

- Depends
- UGREEN NASync DXP2800
- Better fit
The SSD requirement can consume the TerraMaster capacity advantage
If two SATA bays in the F4-425 are allocated to SSDs, only two remain for HDDs. The DXP2800 can instead use its two M.2 slots for SSDs while preserving its two SATA bays, subject to the supported pool layout.

What matters in practice
The differences that matter
Protected capacity with equal 12TB drives
F4-425 gives 36TB and UGREEN NASync DXP2800 gives 12TB before formatting in this example. The difference is 24TB before filesystem overhead.
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 320 seconds for F4-425 and 320 seconds for UGREEN NASync DXP2800. 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, 2.5Gbps or 2.5Gbps. Ignore protocol overhead only for this lower-bound calculation. Optional adapters and aggregated ports are excluded.
The SSD requirement can consume the TerraMaster capacity advantage
If two SATA bays in the F4-425 are allocated to SSDs, only two remain for HDDs. The DXP2800 can instead use its two M.2 slots for SSDs while preserving its two SATA bays, subject to the supported pool layout.
How we reached this conclusion
F4-425 has 4 SATA and 0 M.2 positions. Reserving 2 SATA for SSDs leaves 2 for HDDs. DXP2800 has 2 SATA plus 2 M.2. This is a device-placement calculation, not a performance estimate.
Choice A
TerraMaster, F4-425
F4-425
Four SATA bays give a growing archive more RAID layout choices than a two-bay mirror. A single 2.5GbE port and 4GB memory keep the specification focused on file storage.
- Best matched use
- A growing family archive with four drives
Checked facts
- 4 SATA drive bays and 0 M.2 slots
- 2.5GbE fastest included network port
- 4GB supplied RAM, expandable to 16GB
- Diskless NAS with Intel N5095 processor
Choice B
UGREEN, DXP2800
UGREEN NASync DXP2800
The chassis has 2-bay storage. Its fastest documented network path is 2.5 Gbps.
- Best matched use
- run Plex at home and transcode 4K video
Checked facts
- The chassis has 2-bay storage.
- Its fastest documented network path is 2.5 Gbps.

Meaningful differences
What changes the fit
| What changes | TerraMaster F4-425 | UGREEN NASync DXP2800 | Why it matters |
|---|---|---|---|
| SATA drive bays | 4 | 2 | This changes the disk layouts possible inside the main enclosure. |
| Supplied RAM | 4GB | 8GB | This is the installed memory budget before purchasing upgrade modules. |
| M.2 storage slots | 0 | 2 | Plan SSD cache and storage pools separately from the SATA archive. |
| Processor | Intel N5095 | Intel N100 | 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. |
| SATA bays with supported expansion | 4 | 2 | Expansion requires separately purchased compatible hardware and a supported pool layout. |
What you give up
Every choice has a cost
If you choose TerraMaster F4-425
- No M.2 storage slots are listed and the diskless enclosure requires a separate drive budget.
If you choose UGREEN NASync DXP2800
- One network port provides no second wired path.
Recommendation switch
The decision flips if...
You need four SATA drives for protected capacity
Choose TerraMaster F4-425. F4-425 has four SATA bays. With four equal 12 TB disks, RAID 5 gives 36 TB before formatting compared with the DXP2800's 12 TB SATA mirror.
You want two M.2 slots in a compact server
Choose UGREEN NASync DXP2800. DXP2800 has two M.2 positions alongside its two SATA bays. A supported SSD mirror can therefore leave both SATA positions free for hard drives.
What matters in practice
How to make the call
Start with the required storage layout
The F4-425 makes room for four SATA disks and RAID 5. The DXP2800 uses two SATA bays but adds two M.2 slots and 8GB memory for a compact application server.
Work through the drive budget
The four-bay TerraMaster gives a 36TB RAID 5 example with four 12TB disks. The UGREEN two-drive mirror gives 12TB. A larger advertised raw maximum does not replace this protection calculation.
Check the actual client and application plan
Both use a 2.5GbE link. If the workload is a nightly backup from a gigabit desktop, neither link-rate advantage exists. Choose according to drive count, applications and the desk space available.
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.
