Verdict: Choose the F6-424 if your priority is storing more data in a larger chassis. Select the F4-425 Pro if you need an Intel processor for demanding tasks like virtualization and faster network speeds. Both units provide 8GB of RAM to handle multitasking effectively.
Storage Capacity and Processing Power
number of bays
The TerraMaster F6-424 offers six drive bays, providing significant raw storage potential for large media libraries or extensive data archives. In contrast, the TerraMaster F4-425 Pro limits you to four bays. If your primary goal is maximizing disk capacity within a single chassis, the six-bay model is the clear choice. The four-bay unit requires you to prioritize processing power over raw storage volume. You must decide if you need more slots for future expansion or prefer a more compact footprint with fewer drives installed.
processor cores
Processing architecture differs significantly between these two units. The F4-425 Pro utilizes an Intel N305 processor with eight cores, designed for high-performance multitasking and virtualization. The F6-424 features a quad-core processor. Eight cores allow the Intel model to handle demanding workloads like video editing, containerization, and virtual machines more efficiently. If you plan to run Docker containers, Windows VMs, or heavy transcoding tasks, the eight-core advantage is substantial. The quad-core unit is sufficient for basic file serving but lacks the same computational headroom.
ram capacity
Both NAS drives come equipped with 8GB of RAM. The F6-424 uses DDR5 memory, while the F4-425 Pro lists 8GB of RAM without specifying the generation in its key specs, though its features mention high-performance hardware. Since both provide the same memory capacity, they offer similar baseline capabilities for caching and application handling. This specification does not create a competitive advantage for either unit. You will find equal memory resources for managing simultaneous connections and running local applications on both devices.
network connectivity
The F4-425 Pro includes dual 5GbE network ports, which can be link-aggregated to deliver speeds up to 1020 MB/s. This setup supports high-throughput tasks like 4K streaming and rapid file transfers across your local network. The specifications for the F6-424 do not list network interface details. Without confirmed network specs for the six-bay model, you cannot assume it matches the dual 5GbE capability of the four-bay unit. If fast local network transfer speeds are critical, the Intel model offers a verified advantage.
nvme slots
Cache performance and SSD tiering are handled differently. The F4-425 Pro provides three M.2 NVMe slots for Hyper Cache acceleration, enhancing disk array performance for video editing and virtualization. The specifications for the F6-424 do not mention any M.2 or NVMe support. If you plan to use SSDs for caching or as a fast storage tier, the four-bay Intel model is the only viable option. The six-bay unit lacks this specific hardware feature in its published data, limiting its high-speed caching potential.
Which TerraMaster NAS fits your needs
Users needing maximum raw disk capacity
The F6-424 provides six drive bays compared to the four in the F4-425 Pro. This allows you to install more hard drives in a single chassis. If your priority is storing large media libraries or extensive data archives, the extra bays offer greater total storage potential without requiring additional hardware. The quad-core processor handles basic storage management efficiently.
Users requiring high-speed networking and AI features
The F4-425 Pro features dual 5GbE ports for link-aggregated speeds up to 1020 MB/s. It includes three M.2 NVMe slots for Hyper Cache acceleration. The Intel N305 8-core CPU and TOS 7 AI OS support local AI tasks and natural language commands. These specs benefit users running virtualization, video editing, or complex workflows requiring fast data access.
Developers needing virtualization and Docker support
This model supports native Docker Compose, Portainer, and VirtualBox for running containers and virtual machines. The 8-core Intel processor handles multiple simultaneous tasks better than the quad-core alternative. It also includes enterprise backup tools like HyperLock-WORM and real-time snapshot defense. These features make it suitable for home labs or small business IT environments requiring robust server capabilities.
