TerraMaster Launches AI-Powered F4-425 Pro NAS With TOS 7

TerraMaster has unveiled the F4-425 Pro, a new four-bay flagship network-attached storage system that debuts with TOS 7, which the company describes as the world’s first AI-native operating system. Available globally from June 23, 2026, the device is designed to simplify storage management through natural language interaction while delivering enterprise-grade performance for businesses, creators and advanced home users.

The F4-425 Pro allows users to configure systems, manage storage and deploy applications using conversational commands instead of traditional command-line interfaces. TerraMaster says TOS 7 was built with artificial intelligence at its core, enabling users to perform complex administrative tasks through simple requests. According to the company’s product lead, the platform gives users “an intelligent, conversational data fortress” capable of actively protecting important files.

The NAS features four hot-swappable drive bays supporting 3.5-inch and 2.5-inch SATA HDDs or SSDs, along with three NVMe M.2 2280 SSD slots capable of supporting up to 8TB each. Combined, the system can store as much as 120TB of data while allowing users to separate high-speed SSD storage for active projects from HDD-based archival storage and backups.

Powered by either an Intel N350 or Intel N305 eight-core processor, the F4-425 Pro delivers transfer speeds of up to 1,010 MB/s through dual 5GbE network ports using link aggregation. The N350 version includes 16GB of DDR5 memory, while the N305 model ships with 8GB. The hardware is designed to support demanding workloads including real-time 4K and 8K video editing over a network, multi-user database access, virtual machine hosting and Docker container deployment.

TOS 7 introduces more than 500 modular RESTful APIs and opens low-level system interfaces to AI agents and third-party developers. The operating system supports multi-turn conversations, conditional automation and advanced natural language controls. Users can issue commands such as immediately locking shared folders if ransomware activity is detected, allowing the system to execute security actions automatically.

All AI functions run locally on the device rather than in the cloud. Features such as facial recognition, semantic analysis and automated file organization are processed directly by the NAS hardware, helping to reduce privacy risks by ensuring sensitive data never leaves the system.

TerraMaster is also preparing a developer-focused ecosystem that will include a dedicated Skill Marketplace and software development tools for creating, testing and publishing custom AI-powered applications. The company’s OpenClaw AI Agent enables voice-driven administration and can automatically complete complex tasks, such as creating shared folders and configuring scheduled backups without requiring technical expertise.

Security is a major focus of the platform. The F4-425 Pro includes proactive BBS backup protection featuring HyperLock immutable WORM technology, real-time ransomware detection and an automated 3-2-1-0 backup strategy. When suspicious encryption activity is detected, the system can automatically lock affected folders, quarantine snapshots and issue immediate alerts.

The device is also designed for collaborative creative workflows. TerraMaster says the combination of dual 5GbE networking and high-speed storage allows direct editing of 4K and 8K video files using applications such as Final Cut Pro, Adobe Premiere Pro and DaVinci Resolve without requiring lengthy file transfers or proxy rendering.

For businesses, the NAS supports centralized management of more than 50 computers through permission templates, batch backup operations and security monitoring tools. Developers can also automate Git Pull, Build and Deploy pipelines using OpenClaw with support for GitLab Runner, Jenkins and Ubuntu or Debian virtual machines. Home users can use the system to organize photo libraries with AI-powered sorting by faces, locations and dates, while Dolby Vision and HDR hardware transcoding enable private media streaming.

Additional features include TRAID Flexible RAID for mixing drives of different capacities, TerraSync cross-platform synchronization across NAS, PCs, Macs and mobile devices, hybrid cloud backup support for OneDrive, Google Drive and Dropbox, as well as Docker and virtualization support for expanding applications.

The Intel N350 version of the F4-425 Pro is priced at $799.99, £729.99 or €839.99, while the Intel N305 model starts at $699.99, £639.99 or €739.99. The NAS is available through the TerraMaster Official Store, Amazon, AliExpress, Newegg, Walmart and B&H, with discounts of up to 25% planned during Amazon Prime Day promotions.
