Main trade-off
TerraMaster F2-424
Two bays cannot use RAID 5 or RAID 6.
Head-to-head
TerraMaster F2-424 vs TerraMaster F2-425 Plus N150 8GB: 425 Plus adds a third SSD slot without adding HDD bays
The short answer
The F2-424 supplies an N95 processor, 8GB RAM and dual 2.5GbE ports. The F2-425 Plus N150 keeps the two-drive format while adding dual 5GbE and a third M.2 slot.
Before you choose
The reasoning and the trade-offs
Protected capacity with equal 12TB drives
TerraMaster F2-424 gives 12TB and F2-425 Plus N150 8GB 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 Plus N150 8GB
The three M.2 slots do not turn the two SATA bays into a four-drive hard-disk array.

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, TerraMaster F2-424 gives 12TB and F2-425 Plus N150 8GB gives 12TB before formatting in this example. Changing chassis does not increase this protected capacity.

Keep an onboard M.2 position free after installing a two-SSD mirror
A mirror made from two M.2 SSDs fills every onboard position in the F2-424. The F2-425 Plus has one position left for a separately supported role, which can matter more than its processor-generation change.

What matters in practice
The differences that matter
Protected capacity with equal 12TB drives
TerraMaster F2-424 gives 12TB and F2-425 Plus N150 8GB 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 TerraMaster F2-424 and 160 seconds for F2-425 Plus N150 8GB. 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 5Gbps. Ignore protocol overhead only for this lower-bound calculation. Optional adapters and aggregated ports are excluded.
The third M.2 slot is a concrete layout change
A mirror made from two M.2 SSDs fills every onboard position in the F2-424. The F2-425 Plus has one position left for a separately supported role, which can matter more than its processor-generation change.
How we reached this conclusion
F2-424: 2 slots minus 2 SSDs = 0 remaining. F2-425 Plus: 3 minus 2 = 1 remaining. Confirm pool support, cache restrictions and lane sharing for the actual workload.

Meaningful differences
What changes the fit
| What changes | TerraMaster F2-424 | TerraMaster F2-425 Plus N150 8GB | Why it matters |
|---|---|---|---|
| Fastest included Ethernet port | 2.5GbE | 5GbE | The client, switch and storage must keep up before this port rate helps a transfer. |
| M.2 storage slots | 2 | 3 | Plan SSD cache and storage pools separately from the SATA archive. |
| Processor | Intel N95 | Intel N150 | Media engines, application architecture and concurrency depend on this platform. |
| M.2 position after a two-SSD mirror | No onboard M.2 position remains | One onboard M.2 position remains | A third SSD role can fit without consuming the SATA mirror bays, subject to supported pool layouts. |
What you give up
Every choice has a cost
If you choose TerraMaster F2-424
- Its software experience is less guided than a simple personal cloud.
If you choose TerraMaster F2-425 Plus N150 8GB
- A client and switch capable of 5GbE are required to use the faster port rate. Drives are sold separately.
Recommendation switch
The decision flips if...
Dual 2.5GbE and two M.2 slots meet your plan
Choose TerraMaster F2-424. F2-424 already has dual 2.5 GbE, two M.2 slots and a 32 GB memory ceiling. Its two SATA bays provide the same mirrored hard-drive capacity.
You need 5GbE and a third M.2 position
Choose TerraMaster F2-425 Plus N150 8GB. F2-425 Plus adds 5 GbE and a third M.2 position. After two M.2 SSDs form a supported mirror, one onboard M.2 position remains.
What matters in practice
How to make the call
Start with the required storage layout
The F2-424 supplies an N95 processor, 8GB RAM and dual 2.5GbE ports. The F2-425 Plus N150 keeps the two-drive format while adding dual 5GbE and a third M.2 slot.
Work through the drive budget
Both officially support 32GB memory and a two-drive SATA mirror. Those limits remain shared, so the decision should follow network equipment and the planned M.2 layout.
Check the actual client and application plan
A third M.2 position matters when two SSDs form a mirror and another storage role is required. Verify SSD compatibility and lane sharing before assuming that three installed devices can all sustain full advertised SSD speed.
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.
