Main trade-off
UGREEN NASync DXP2800
Two SATA bays cap growth and rule out parity layouts.
Head-to-head
UGREEN NASync DXP2800 vs TerraMaster F2-425: DXP2800 keeps SSD applications separate from SATA backups
The short answer
Keep the DXP2800 on the shortlist if an M.2 application pool or 8GB of supplied memory will be used. The F2-425 fits a simpler archive that stays on SATA drives.
Before you choose
The reasoning and the trade-offs
Protected capacity with equal 12TB drives
UGREEN NASync DXP2800 gives 12TB and F2-425 gives 12TB 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
TerraMaster F2-425
Two SATA bays leave no room to add a third data drive to the same chassis.

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, UGREEN NASync DXP2800 gives 12TB and F2-425 gives 12TB before formatting in this example. Changing chassis does not increase this protected capacity.

Several local services sharing the supplied RAM
UGREEN NASync DXP2800 supplies 8 GB RAM and supports 16 GB. TerraMaster F2-425 supplies 4 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.
- UGREEN NASync DXP2800
- Better fit
- TerraMaster F2-425
- Depends
Keep a SATA mirror and a separate two-drive M.2 SSD mirror inside the chassis
A two-SSD mirrored application pool can occupy the DXP2800 M.2 slots while both SATA bays hold the bulk mirror. The F2-425 has zero M.2 slots, so that exact four-device layout is unavailable internally.

What matters in practice
The differences that matter
Protected capacity with equal 12TB drives
UGREEN NASync DXP2800 gives 12TB and F2-425 gives 12TB 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 320 seconds for UGREEN NASync DXP2800 and 320 seconds for F2-425. 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.
A separate SSD mirror fits only the DXP2800
A two-SSD mirrored application pool can occupy the DXP2800 M.2 slots while both SATA bays hold the bulk mirror. The F2-425 has zero M.2 slots, so that exact four-device layout is unavailable internally.
How we reached this conclusion
Layout requires 2 SATA bays plus 2 M.2 slots. DXP2800 has 2 plus 2. F2-425 has 2 plus 0. Confirm supported M.2 pool configuration and SSD models.

What you give up
Every choice has a cost
If you choose UGREEN NASync DXP2800
- One network port provides no second wired path.
If you choose TerraMaster F2-425
- There are no M.2 slots. Storage drives are purchased separately.
Recommendation switch
The decision flips if...
You need two M.2 slots beside a SATA mirror
Choose UGREEN NASync DXP2800. DXP2800 keeps two SATA archive drives while its two M.2 positions can host a separately supported SSD layout. Its supplied 8 GB also exceeds the F2-425's 4 GB.
You want a SATA-only archive with 4GB RAM
Choose TerraMaster F2-425. F2-425 has the same two SATA bays and 2.5 GbE port rate. It covers a SATA-only mirror without relying on M.2 slots that this chassis does not have.
What matters in practice
How to make the call
Start with the required storage layout
Keep the DXP2800 on the shortlist if an M.2 application pool or 8GB of supplied memory will be used. The F2-425 fits a simpler archive that stays on SATA drives.
Work through the drive budget
Both chassis stop at two SATA bays. Buying the DXP2800 does not increase the size of a two-drive mirror, so calculate the future library before choosing the enclosure.
Check the actual client and application plan
The DXP2800 offers two M.2 slots and twice the supplied memory. The F2-425 still has the same 2.5GbE port rate, so the upgrade pays for storage layout and applications rather than a faster Ethernet link.
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.
