The catch
TerraMaster F4-425 Plus N150 16GB
A 10GbE client cannot link at 10GbE to this chassis, since 5GbE is the fastest port included.
Side by side
TerraMaster F4-425 Plus N150 16GB vs QNAP TS-464-8G-US Compared: TerraMaster comes with 5GbE, and QNAP leaves a route for a card upgrade
Quick verdict
5GbE and 16GB memory come with the F4-425 Plus. The TS-464 offers QTS and a PCIe expansion slot, which helps when a supported adapter is part of a defined plan.
Before you buy
Why, and what it costs you
Protected capacity when all drives are 12TB
In this example, F4-425 Plus N150 16GB comes to 36TB and QNAP TS-464-8G-US to 36TB before formatting. Moving to another chassis does not add protected capacity.
Where this comes from
Suppose each SATA bay holds a supported 12TB disk. A two-bay RAID 1 gives the usable capacity of one disk. With three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. The layout is only an illustration. It is not storage that comes included, and it is not a backup.
The catch
QNAP TS-464-8G-US
Setup takes care given the interface's many controls.

What this page compares
Which of F4-425 Plus N150 16GB and TS-464-8G-US fits depends on protected storage, included networking and the exact SSD or application layout you need.
It comes down to faster built-in ports or the QNAP expansion path.
Which one fits
Pick the situations that sound like you
Protected archive built from 12 TB disks filling every internal SATA bay
The example puts two disks in RAID 1 and three or more in RAID 5. Before formatting, F4-425 Plus N150 16GB yields 36TB, against 36TB for QNAP TS-464-8G-US. Swapping the chassis does not add protected capacity.

Multiple local services dividing up the supplied RAM
TerraMaster F4-425 Plus N150 16GB supplies 16 GB RAM and supports 32 GB. QNAP TS-464-8G-US supplies 8 GB. QNAP’s current exact 8G specification lists SODIMM since January 2024 and a 16GB maximum, while its January 2026 family manual still labels 8G memory non-expandable. The retained ASIN does not establish the supplied physical revision. Confirm that revision with the seller or QNAP before planning an upgrade. Neither document supports more than 16GB. Compare the stated application memory requirement with the supplied configuration before budgeting for an upgrade. RAM capacity alone does not establish application speed.

Fit three M.2 devices with no expansion card to buy
After two SSDs go into a mirror, the F4-425 Plus still has one M.2 position left. On the TS-464 that same pair fills both onboard positions, so any other M.2 device needs a supported expansion route.

In practice
Differences you will notice
Protected capacity when all drives are 12TB
In this example, F4-425 Plus N150 16GB comes to 36TB and QNAP TS-464-8G-US to 36TB before formatting. Moving to another chassis does not add protected capacity.
How we worked this out
Suppose each SATA bay holds a supported 12TB disk. A two-bay RAID 1 gives the usable capacity of one disk. With three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. The layout is only an illustration. It is not storage that comes included, and it is not a backup.
100GB moved at the speed ceiling of the included port
Line rate sets a lower bound of 160 seconds for F4-425 Plus N150 16GB and 320 seconds for QNAP TS-464-8G-US. Real copies take longer. Put a 1GbE client in the path and the bound is 800 seconds for both.
How we worked this out
Start with decimal 100GB × 8 = 800 gigabits. Then divide 800 by the fastest included port rate, 5Gbps or 2.5Gbps. Protocol overhead is left out of this lower-bound calculation alone, and so are optional adapters and aggregated ports.
Once an SSD mirror exists, one more M.2 slot matters
After two SSDs go into a mirror, the F4-425 Plus still has one M.2 position left. On the TS-464 that same pair fills both onboard positions, so any other M.2 device needs a supported expansion route.
How we worked this out
For F4-425 Plus, 3 minus 2 = 1. For TS-464, 2 minus 2 = 0 onboard M.2 positions remaining. A PCIe card should not be counted until its compatibility and lane needs are confirmed.

Spec by spec
Where they really differ
| Spec | TerraMaster F4-425 Plus N150 16GB | QNAP TS-464-8G-US | In practice |
|---|---|---|---|
| Fastest included Ethernet port | 5GbE | 2.5GbE | This port rate only helps a transfer if the client, switch and storage keep up. |
| Supplied RAM | 16GB | 8GB | This figure is the memory already installed, before any upgrade modules are bought. |
| Supported RAM ceiling | 32GB | 16GB in current SODIMM specification, physical revision unconfirmed | Since January 2024, QNAP’s current exact 8G specification has listed SODIMM and a 16GB maximum. Its January 2026 family manual, however, still labels 8G memory non-expandable. The retained ASIN does not tell you which physical revision is supplied, so confirm that revision with the seller or QNAP before planning an upgrade. Neither document supports more than 16GB. |
| M.2 storage slots | 3 | 2 | Treat SSD cache and storage pools as a separate plan from the SATA archive. |
| Processor | Intel N150 | Intel Celeron N5095 | The platform determines the media engines, the application architecture and the concurrency. |
| Software and expansion route | TOS | QTS with PCIe expansion slot | Pick the applications and supported add-ons the job calls for. |
Trade-offs
What each pick costs you
With TerraMaster F4-425 Plus N150 16GB
- What is described here is the N150 16GB listing. Check the N95 and other memory variants on their own. Drives are not included.
With QNAP TS-464-8G-US
- A separate PCIe adapter is required for 10GbE.
Change of plan
When the answer changes
Built-in 5GbE and three M.2 positions are required
Go with TerraMaster F4-425 Plus N150 16GB. F4-425 Plus comes with 5 GbE and three M.2 positions, and reaching that supplied port rate needs no network expansion card.
QTS or PCIe expansion is a defined requirement for you
Go with QNAP TS-464-8G-US. QTS and a PCIe expansion path come with TS-464. Check the application or adapter you need against QNAP's compatibility list before letting it decide the purchase.
Decision guide
How to decide
First, pin down the storage layout you need
5GbE and 16GB memory come with the F4-425 Plus. The TS-464 offers QTS and a PCIe expansion slot, which helps when a supported adapter is part of a defined plan.
Count what the drive budget allows
Four SATA bays come on both. TerraMaster has three M.2 slots against QNAP’s two, which can matter when a mirrored SSD pool leaves another SSD role to fill. Check the actual bandwidth of each slot.
Look at the client and apps you will really use
2.5GbE ports ship on the TS-464. A plan for faster networking has to count a compatible expansion card and what it costs. Having two ports does not by itself double the speed of a normal single client connection.
What this page can’t tell you
- Capacity examples assume equal 12TB drives, counted before formatting, snapshots and filesystem overhead.
- Treat Ethernet calculations as lower bounds, since disk performance, network protocol and other traffic add time.
- Neither application speed nor a VM count follows from memory capacity alone.
