TerraMaster has officially introduced its latest flagship 4-bay NAS, the F4-425 Pro, bringing a combination of AI-powered software, upgraded networking, and modern storage features to creators, businesses, developers, and home users. The new model is launching globally on June 23 and will be available with a limited-time 20% discount during Amazon Prime Day. The company is also extending discounts across several NAS and DAS products as part of its wider Prime Day promotion.
The F4-425 Pro is powered by TerraMaster’s latest TOS 7 operating system, which the company describes as the world’s first AI-native NAS platform. Rather than relying entirely on traditional menus and manual configuration, the system introduces natural language controls that allow users to manage storage, deploy applications, create backups, and configure system settings through conversational commands.
Under the hood, the NAS is equipped with Intel’s N350 processor featuring eight cores and a low 7W power consumption design. The system also includes 16GB of DDR5 memory and dual 5GbE Ethernet ports. When link aggregation is enabled, TerraMaster claims the NAS can deliver transfer speeds of up to 1010 MB/s, making it suitable for bandwidth-intensive workloads such as 4K and 8K video editing, virtualization, Docker deployments, and multi-user collaboration.
According to TerraMaster, TOS 7 has been redesigned to support AI-driven workflows from the ground up. The operating system includes more than 500 modular RESTful APIs, allowing developers and AI agents to interact directly with system functions. The platform can also process complex natural language requests, handle multi-step conversations, and automate storage-related tasks without requiring users to navigate through multiple configuration menus.
TerraMaster also integrates OpenClaw, an AI-driven assistant that helps streamline NAS administration. Users can issue simple text-based requests for tasks like folder creation, backup management, and snapshot configuration, reducing the time required to manage storage and system settings.
The company has also placed a strong focus on privacy and security. AI-powered functions such as facial recognition, file categorization, and semantic analysis are processed directly on the NAS hardware instead of being sent to external cloud services. This approach helps users keep their data under local control while still benefiting from AI-assisted features.

TerraMaster says the F4-425 Pro is designed to support a wide range of use cases. Creative professionals can work directly with large video projects over high-speed network connections, while businesses can simplify storage management and backup operations. Developers can deploy virtual machines, containers, and automated workflows, while home users can create private media libraries with AI-assisted organization and hardware transcoding support for Dolby Vision and HDR content.
With upgraded hardware, AI-focused software, and a growing ecosystem of storage and productivity tools, the TerraMaster F4-425 Pro arrives as one of the company’s most advanced NAS solutions to date. The launch also comes at a time when demand for private cloud storage and locally processed AI features continues to grow among both professional and consumer users.
