TerraMaster F6-424 vs F4-425 Pro
drive bays
Storage capacity starts with the number of drive bays. The TerraMaster F6-424 offers six drive bays, giving you more physical slots for hard drives. This model is ideal if you plan to store large media libraries or need significant raw capacity. The TerraMaster F4-425 Pro provides four drive bays. While it has fewer slots, it supports TRAID technology, which allows you to mix drive capacities and expand arrays online. You should choose the F6-424 if maximizing the number of drives is your priority. The F4-425 Pro is better if you prefer flexibility in drive sizes and expansion options over sheer bay count.
ram capacity
Memory plays a key role in multitasking and virtualization. The TerraMaster F4-425 Pro comes with 16GB of DDR5 RAM. This larger amount of memory helps when running multiple Docker containers, virtual machines, or heavy database queries simultaneously. The TerraMaster F6-424 includes 8GB of DDR5 RAM. While sufficient for basic file serving and light tasks, it may limit the number of concurrent virtual machines you can run. If your workflow involves heavy virtualization or running many services at once, the F4-425 Pro provides double the memory headroom. For simple storage, both amounts are functional.
processor cores
Processing power affects how quickly the NAS handles requests. The TerraMaster F4-425 Pro is equipped with an Intel N350 8-Core CPU. This higher core count helps with parallel tasks, such as transcoding multiple video streams or running complex AI features in TOS 7. The TerraMaster F6-424 uses a Quad-Core processor. While efficient for general storage duties, it has fewer cores to distribute workloads. If you plan to use the NAS for intensive multimedia streaming or virtualization, the eight cores in the F4-425 Pro offer a clear performance advantage. The quad-core in the F6-424 is adequate for standard file storage.
network connectivity
Network speed determines how fast you can transfer files across your local area network. The TerraMaster F4-425 Pro features dual 5GbE ports. These ports can be link-aggregated to provide a combined bandwidth of 10Gb, allowing for faster data transfers and reduced network congestion. The specifications for the TerraMaster F6-424 do not list its network ports. You must check the manual or product page to confirm its connectivity. If the F6-424 only has single Gigabit ports, the F4-425 Pro will significantly outperform it in large file transfers. Dual 5GbE is a strong feature for high-speed local access.
nvme slots
Cache performance and speed are enhanced by NVMe SSDs. The TerraMaster F4-425 Pro includes three M.2 NVMe slots. These slots support Hyper Cache acceleration, which speeds up read and write operations for frequently accessed data. This is useful for video editing and database work. The specifications for the TerraMaster F6-424 do not mention any M.2 NVMe slots. Without these slots, you cannot add NVMe cache to improve performance. If you rely on fast caching for performance boosts, the F4-425 Pro is the superior choice. The F6-424 lacks this specific hardware expansion capability based on the provided data.
Which TerraMaster NAS fits your needs
Users needing maximum raw storage capacity
Choose the F6-424 if you need more physical drive slots. It offers six bays compared to the four in the F4-425 Pro. This model provides six drive bays for large media libraries or significant raw capacity. The quad-core processor and 8GB DDR5 RAM handle basic storage tasks efficiently without requiring extra hardware.
Users requiring high performance and expansion
Select the F4-425 Pro for superior processing power and connectivity. It features an 8-core Intel N350 CPU and 16GB DDR5 RAM. The unit includes three M.2 NVMe slots for Hyper Cache acceleration and dual 5GbE ports for link-aggregated bandwidth. This setup supports demanding tasks like virtualization and high-speed file transfers effectively.
Developers and small business IT teams
The F4-425 Pro supports native Docker Compose, Portainer, and VirtualBox. This allows you to run containers, Windows VMs, and Linux environments simultaneously. The 16GB RAM and 8-core processor provide the headroom needed for these workloads. The dual 5GbE ports ensure fast network access for your development and business applications.

Frequently asked questions
Which TerraMaster NAS has more RAM?
The TerraMaster F4-425 Pro has 16GB of DDR5 RAM. This is double the 8GB found in the F6-424. More memory helps when running multiple virtual machines or heavy applications simultaneously. If your workflow relies on multitasking, the extra RAM in the four-bay model provides a clear performance advantage.
Which model offers better processing power?
The TerraMaster F4-425 Pro features an eight-core processor. In contrast, the F6-424 uses a quad-core chip. Eight cores allow for faster data processing and smoother operation of resource-intensive tasks. You should choose the four-bay model if computational speed is a higher priority than raw storage space.
Can I expand storage with the F4-425 Pro?
The F4-425 Pro supports four drive bays. While this is fewer slots than the six-bay F6-424, you can still configure RAID for redundancy or performance. If you need maximum physical capacity for large media libraries, the six-bay unit is the better choice. Otherwise, the four-bay model suffices for most users.
Is the F6-424 suitable for home servers?
Yes, the F6-424 is ideal for growing home servers. It provides six drive bays for ample storage capacity. Although it has only 8GB of RAM, it handles standard file sharing and media streaming well. It is a practical choice if you prioritize disk space over high-end processing capabilities.
What is the weight difference between the two models?
The F6-424 weighs 7.5 pounds. The F4-425 Pro is lighter at 6.39 pounds. This difference comes from the extra drive bays and internal structure of the six-bay unit. If you plan to move the NAS frequently, the lighter four-bay model might be easier to handle.
Do both models use DDR5 memory?
Yes, both the F6-424 and F4-425 Pro use DDR5 RAM. This modern memory type offers better bandwidth and efficiency than older generations. The F4-425 Pro takes advantage of this with 16GB, while the F6-424 uses 8GB. Both benefit from the speed improvements inherent in DDR5 technology.
