Spec Comparison: 6-Bay vs 4-Bay Models
Number of Bays
Storage capacity is often the primary driver for NAS selection. The TerraMaster F6-424 offers six drive bays, providing significant room for large media libraries or extensive data archives. This configuration allows you to install more drives for higher total capacity or redundancy. In contrast, the TerraMaster F4-425 Pro features four drive bays. While it has fewer slots, it still supports substantial storage volumes. You should choose the six-bay model if raw capacity and drive count are your top priorities. The four-bay option is better if you prefer a more compact footprint or already have ample storage elsewhere.
Processor Cores
Processing power determines how well the NAS handles multitasking, virtualization, and transcoding. The TerraMaster F4-425 Pro is equipped with an Intel N305 or N300 processor featuring eight cores. This higher core count can manage more simultaneous tasks, such as running multiple Docker containers or virtual machines, with greater efficiency. The TerraMaster F6-424 uses a quad-core processor. While sufficient for basic file serving and media streaming, it may struggle more under heavy computational loads compared to the eight-core unit. If you plan to run intensive applications or virtualization, the eight-core architecture offers a clear advantage.
RAM Capacity
Random Access Memory (RAM) supports system responsiveness and application performance. Both the TerraMaster F6-424 and the TerraMaster F4-425 Pro include 8GB of RAM. However, the F6-424 specifies DDR5 memory, which offers higher bandwidth and improved efficiency over previous generations. The F4-425 Pro lists 8GB of RAM without specifying the generation in the provided key specs. In practice, this means both units have the same capacity for caching and multitasking. The DDR5 technology in the six-bay model may provide slightly faster data access speeds. For most users, the identical capacity ensures smooth operation for both devices.
M.2 NVMe Slots
Solid State Drive (SSD) caching can significantly boost read and write speeds for frequently accessed files. The TerraMaster F4-425 Pro includes three M.2 NVMe slots. This allows you to install multiple NVMe drives for Hyper Cache acceleration, maximizing disk array performance for tasks like video editing or virtualization. The TerraMaster F6-424 does not list any M.2 NVMe slots in its specifications. This means it lacks dedicated hardware acceleration for SSD caching. If you rely on fast random access speeds for development or media creation, the three-slot configuration in the four-bay model is a substantial feature that the six-bay unit does not offer.
Network Connectivity
Network speed affects how quickly you can transfer files between the NAS and your devices. The TerraMaster F4-425 Pro features dual 5GbE ports. These ports can be link-aggregated to deliver speeds up to 1020 MB/s, providing high throughput for large file transfers. The TerraMaster F6-424 does not list specific network port details in the provided data. Without this information, we cannot confirm its maximum network speed. If you have a high-speed network infrastructure, the dual 5GbE ports on the F4-425 Pro ensure you can fully utilize that bandwidth. The six-bay model’s network capabilities remain undefined in the current specifications.
Choose the right NAS for your needs
You need maximum drive capacity for archives
The TerraMaster F6-424 provides six drive bays, offering more space for large media libraries or extensive data archives. This configuration allows you to install additional drives for higher total storage capacity or enhanced redundancy. If your priority is physical drive count over raw processing speed, this six-bay enclosure is the practical choice for expanding your storage footprint.
You require high performance for virtualization
The TerraMaster F4-425 Pro features an Intel N305/N300 eight-core CPU and three M.2 NVMe slots with Hyper Cache acceleration. This hardware setup handles multiple tasks simultaneously with ease, making it ideal for video editing, virtualization, and running Docker containers or Windows VMs. The dual 5GbE ports also deliver link-aggregated speeds up to 1020 MB/s for faster data access.
You want AI features and modern software
This model runs TOS 7, an AI-native operating system that integrates the OpenClaw AI agent for natural language commands. It supports hardware 4K decoding for streaming and includes the TNAS Mobile app for remote management. The exclusive TRAID technology allows for online array expansion without interrupting services, while enterprise backup suites provide robust ransomware defense for your data.

Frequently asked questions
Which NAS is better for virtualization tasks?
The TerraMaster F4-425 Pro is the better choice for virtualization. It features an 8-core processor, which provides the raw processing power needed for running multiple virtual machines or AI tools efficiently. While the 6-bay model has more drive slots, its quad-core chip offers less computational headroom for heavy multitasking workloads.
Does the 6-bay model support DDR5 RAM?
Yes, the TerraMaster F6-424 is designed for users prioritizing DDR5 speed. It comes with 8GB of RAM, which helps with data caching and system responsiveness. This memory type generally offers faster bandwidth than older standards, making it suitable for handling larger files or more simultaneous connections without significant bottlenecks.
How much physical space does each unit take up?
The 6-bay TerraMaster F6-424 measures 9.06 inches in length and 5.91 inches in width. The 4-bay F4-425 Pro is slightly wider at 7.13 inches but shorter in length at 8.62 inches. Both units are compact enough for desktop use, though the 6-bay version weighs slightly more at 7.5 pounds compared to 6.39 pounds.
Can I use the 4-bay NAS for large media archives?
You can use it, but it holds fewer drives than the 6-bay option. The TerraMaster F4-425 Pro has only four bays, limiting your maximum raw storage capacity compared to the F6-424. If your archive is massive, the extra two bays on the 6-bay model provide more flexibility for adding drives or creating redundant arrays.
What is the main difference in processing power between these two?
The primary difference is the core count. The TerraMaster F4-425 Pro uses an 8-core processor, ideal for compute-heavy tasks like transcoding or virtualization. The TerraMaster F6-424 uses a quad-core processor, which is sufficient for standard file serving and backups but offers less power for intensive computational workloads.
Is the 6-bay NAS suitable for home servers with high storage needs?
It is a practical choice for home servers needing high capacity. With six bays and 8GB of RAM, it balances storage space with enough memory for smooth operation. It fits users who prioritize having room for many drives over having the highest possible processing speed for complex applications.
