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 TerraMaster F4-424 Pro 32GB: 425 Plus adds network speed, 424 Pro supplies 32GB for services
The short answer
The F4-425 Plus adds dual 5GbE ports and a third M.2 slot. The F4-424 Pro configuration here supplies 32GB RAM for a workload already planned around that memory budget.
Before you choose
The reasoning and the trade-offs
Protected capacity with equal 12TB drives
F4-425 Plus N150 16GB gives 36TB and TerraMaster F4-424 Pro 32GB 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
TerraMaster F4-424 Pro 32GB
The exact 32GB variation is excessive for basic file storage.

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 TerraMaster F4-424 Pro 32GB 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. TerraMaster F4-424 Pro 32GB supplies 32 GB and supports 32 GB. Compare the stated application memory requirement with the supplied configuration before budgeting for an upgrade. RAM capacity alone does not establish application speed.

Cover a 24 GB service allocation with the supplied RAM
A workload that explicitly allocates 24GB across services exceeds the F4-425 Plus supplied 16GB by 8GB, while the F4-424 Pro supplied 32GB leaves 8GB before other overhead. The Plus can reach the requirement only after an appropriate memory upgrade.

What matters in practice
The differences that matter
Protected capacity with equal 12TB drives
F4-425 Plus N150 16GB gives 36TB and TerraMaster F4-424 Pro 32GB 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 320 seconds for TerraMaster F4-424 Pro 32GB. 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 2.5Gbps. Ignore protocol overhead only for this lower-bound calculation. Optional adapters and aggregated ports are excluded.
A 24GB allocation requires different first purchases
A workload that explicitly allocates 24GB across services exceeds the F4-425 Plus supplied 16GB by 8GB, while the F4-424 Pro supplied 32GB leaves 8GB before other overhead. The Plus can reach the requirement only after an appropriate memory upgrade.
How we reached this conclusion
Scenario uses an explicit 24GB service allocation. 16 minus 24 = negative 8GB. 32 minus 24 = 8GB. Leave additional memory for the OS and filesystem cache in the final plan.

What changes the fit
| What changes | TerraMaster F4-425 Plus N150 16GB | TerraMaster F4-424 Pro 32GB | Why it matters |
|---|---|---|---|
| Fastest included Ethernet port | 5GbE | 2.5GbE | The client, switch and storage must keep up before this port rate helps a transfer. |
| Supplied RAM | 16GB | 32GB | This is the installed memory budget before purchasing upgrade modules. |
| M.2 storage slots | 3 | 2 | Plan SSD cache and storage pools separately from the SATA archive. |
| Processor | Intel N150 | Intel Core i3-N305 | Media engines, application architecture and concurrency depend on this platform. |
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 TerraMaster F4-424 Pro 32GB
- There is no built-in 10GbE.
Recommendation switch
The decision flips if...
You need dual 5GbE and a third M.2 slot
Choose TerraMaster F4-425 Plus N150 16GB. F4-425 Plus includes dual 5 GbE ports and three M.2 slots. F4-424 Pro instead includes 2.5 GbE and two M.2 positions.
Your services already require 32GB RAM
Choose TerraMaster F4-424 Pro 32GB. F4-424 Pro supplies 32 GB, compared with 16 GB in F4-425 Plus. A workload requiring more than 16 GB can therefore avoid an immediate memory replacement.
What matters in practice
How to make the call
Start with the required storage layout
The F4-425 Plus adds dual 5GbE ports and a third M.2 slot. The F4-424 Pro configuration here supplies 32GB RAM for a workload already planned around that memory budget.
Work through the drive budget
The Pro has an eight-core i3-N305 while this Plus uses a quad-core N150. Core counts and RAM do not establish a measured performance result, but they identify different application budgets.
Check the actual client and application plan
The Plus starts with 16GB and supports 32GB. The Pro already supplies 32GB. For a system that needs 24GB allocated before filesystem cache, the Pro avoids an immediate memory replacement.
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.
