The catch
TerraMaster F4-424 Pro 32GB
That particular 32GB variation is overkill for basic file storage.
Side by side
TerraMaster F4-424 Pro 32GB vs QNAP TS-464-8G-US Compared: 32GB supplied for services, or a PCIe path that is supported for upgrades
Quick verdict
The F4-424 Pro is right when the planned services need its supplied 32GB RAM. The TS-464 is right when QTS or a supported PCIe card is a defined requirement.
Before you buy
Why, and what it costs you
Protected capacity when all drives are 12TB
Before formatting, this example gives 36TB with TerraMaster F4-424 Pro 32GB and 36TB with QNAP TS-464-8G-US. 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.

- Why pick it
- 32GB is what your service memory budget already calls for

What this page compares
Which of F4-424 Pro and TS-464-8G-US fits depends on protected storage, included networking and the exact SSD or application layout you need.

Which one fits
Pick the situations that sound like you
Protected archive built from 12 TB disks filling every internal SATA bay
Here two disks use RAID 1 and three or more use RAID 5. TerraMaster F4-424 Pro 32GB gives 36TB and QNAP TS-464-8G-US gives 36TB before formatting. Switching chassis does not raise this protected capacity.

Multiple local services dividing up the supplied RAM
TerraMaster F4-424 Pro 32GB supplies 32 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 a 24 GB service allocation inside the documented RAM ceiling
The F4-424 Pro supplies 32GB and can cover an explicit 24GB service allocation with 8GB left before other overhead. Even the current 16GB specification is 8GB below that allocation. 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.

In practice
Differences you will notice
Protected capacity when all drives are 12TB
Before formatting, this example gives 36TB with TerraMaster F4-424 Pro 32GB and 36TB with QNAP TS-464-8G-US. 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 320 seconds for TerraMaster F4-424 Pro 32GB 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
Decimal 100GB × 8 = 800 gigabits. Take the fastest included port rate, 2.5Gbps or 2.5Gbps, and divide 800 by it. Protocol overhead is ignored here only because this is a lower-bound calculation. Optional adapters and aggregated ports are left out.
The stock QNAP platform is ruled out by a 24GB service allocation
The F4-424 Pro supplies 32GB and can cover an explicit 24GB service allocation with 8GB left before other overhead. Even the current 16GB specification is 8GB below that allocation. 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.
How we worked this out
Scenario is 24GB of planned service memory. Pro supplied 32 minus 24 = 8GB. The current 16GB specification minus 24GB = negative 8GB. The family manual instead describes non-expandable 8GB, and the supplied revision remains unverified. Unsupported memory configurations are excluded.

Trade-offs
What each pick costs you
With TerraMaster F4-424 Pro 32GB
- 10GbE is not built in.
With QNAP TS-464-8G-US
- A separate PCIe adapter is required for 10GbE.
Change of plan
When the answer changes
32GB is what your service memory budget already calls for
Go with TerraMaster F4-424 Pro 32GB. F4-424 Pro supplies 32 GB and can cover a defined 24 GB service allocation with 8 GB left before other overhead. Both documented TS-464 memory configurations fall below that allocation. 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.
QTS and the supported PCIe adapter path are required
Go with QNAP TS-464-8G-US. QTS and a supported PCIe adapter route come with TS-464. To justify its smaller supplied and maximum memory budget, you need a real software or expansion requirement.
Decision guide
How to decide
First, pin down the storage layout you need
The F4-424 Pro is right when the planned services need its supplied 32GB RAM. The TS-464 is right when QTS or a supported PCIe card is a defined requirement.
Count what the drive budget allows
Four SATA bays, two M.2 slots and dual 2.5GbE ports are shared by the two systems. Those headline counts name no speed winner and give no different protected archive capacity.
Look at the client and apps you will really use
An eight-core i3-N305 powers the Pro, and an N5095 the TS-464. Before assigning a speed multiplier based on processor naming or core count, compare application compatibility and measured requirements.
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.
