TerraMaster has unveiled its latest flagship F4-425 Pro, a four-bay network-attached storage (NAS) solution powered by TOS 7, which the company describes as the world’s first AI-native NAS operating system. Designed for creators, businesses, developers, and home users, the new platform combines enterprise-grade hardware with artificial intelligence to simplify storage management while enhancing performance, security, and privacy.
Unlike conventional NAS systems that often require complex setup procedures and command-line expertise, the F4-425 Pro introduces an AI-driven experience that enables users to configure storage, deploy applications, manage backups, and administer the system using natural language commands. Users can simply describe the task they want to perform, allowing the integrated AI assistant to execute the required actions automatically.
According to TerraMaster, TOS 7 has been developed with AI at its core, enabling conversational interaction while ensuring all AI processing remains on the NAS itself. By processing data locally rather than in the cloud, the platform enhances privacy and minimizes the risk of sensitive information being exposed.
“TOS 7 stands as the industry’s first operating system engineered for AI right at its core,” said a TerraMaster product executive. “Combined with the F4-425 Pro, it enables creators, small businesses and home users to build an intelligent, conversational private data platform that actively protects their most valuable digital assets.”
The F4-425 Pro is powered by Intel’s 8-core N350 processor, which delivers high computing performance while maintaining an energy-efficient 7W power consumption. The system includes 16GB of DDR5 memory and dual 5GbE Ethernet ports that support link aggregation, enabling transfer speeds of up to 1,010MB/s.
The hardware is designed to handle demanding workloads such as native 4K and 8K video editing, virtualization, Docker containers, and simultaneous access by multiple users. The combination of high-speed networking and powerful processing enables users to edit large media files directly from the NAS without the need for lengthy file transfers.
A key differentiator is TOS 7’s AI-native architecture, which provides more than 500 modular RESTful APIs that allow AI agents and third-party developers to integrate directly with the operating system. The platform supports multi-turn conversations, contextual commands, and workflow automation, making it easier for users to manage complex storage environments without technical expertise.
The operating system also delivers on-device AI capabilities, including facial recognition, semantic file analysis, and intelligent photo organization. Since all AI processing occurs locally, user data never leaves the NAS, addressing growing concerns around privacy, security, and data sovereignty.
TerraMaster also plans to introduce a dedicated Skill Marketplace, where developers will be able to build, publish, and share AI-powered applications, expanding the platform’s capabilities over time.
Another highlight is OpenClaw, TerraMaster’s built-in AI agent that enables users to control the NAS through everyday language. Rather than manually configuring storage or backup settings, users can simply issue voice or text commands such as creating shared folders, scheduling snapshots, or setting permission policies. OpenClaw interprets the requests and performs the required tasks automatically, significantly simplifying NAS administration.
Security is another major focus of the F4-425 Pro. The platform integrates TerraMaster’s BBS Backup Suite, which combines real-time ransomware detection, HyperLock immutable WORM technology, and an automated 3-2-1-0 backup strategy. If suspicious encryption activity is detected, the system automatically locks affected folders, isolates backup snapshots, and sends alerts to administrators, providing proactive protection against ransomware attacks.
TerraMaster has designed the F4-425 Pro to support a wide range of users. Creative professionals can take advantage of dual 5GbE networking for collaborative editing with applications such as Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro, enabling direct editing of high-resolution media stored on the NAS.
For small and medium-sized businesses, the platform simplifies IT management by allowing administrators to deploy user permissions, automate backups across multiple systems, and monitor security through natural language commands.
Developers can integrate OpenClaw with tools including GitLab Runner and Jenkins to automate CI/CD workflows while running Ubuntu or Debian virtual machines directly on the device. Home users, meanwhile, benefit from automatic mobile backups, AI-powered photo organization, facial recognition, and hardware transcoding for Dolby Vision and HDR content to build a private multimedia library.
The F4-425 Pro also offers TRAID Flexible RAID, enabling users to combine drives of different capacities and expand storage without migrating existing data. TerraSync provides near real-time synchronization across Windows PCs, Macs, mobile devices, and NAS systems with version history support.
In addition, the NAS supports two-way synchronization with cloud storage services including Microsoft OneDrive, Google Drive, and Dropbox, allowing users to combine private storage with cloud collaboration. Built-in support for Docker containers and virtual machines further extends the platform, enabling organizations to deploy business and development applications directly on the NAS.
By combining AI-native software, enterprise-grade hardware, intelligent automation, and comprehensive data protection, TerraMaster positions the F4-425 Pro as a next-generation NAS platform designed to simplify private cloud storage while meeting the evolving needs of businesses, creators, developers, and home users.
