TerraMaster, a leading global private cloud storage brand, today announced the global debut of its latest 4-bay flagship NAS, the F4-425 Pro, scheduled for June 23 to coincide with Amazon Prime Day. Powered by TOS 7, the world's first AI-native operating system, the F4-425 Pro redefines the private cloud storage eperience with natural language interaction, localized intelligent computing, and enterprise-grade performance.

To celebrate the launch, the F4-425 Pro will be offered at a limited-time 20% discount during Prime Day, along with several other best-selling NAS and DAS products.

Leave Legacy NAS Behind—Step Into an AI-Native Private Workflow
Far more than a conventional network-attached storage device, the F4-425 Pro serves as an AI-native storage hub built for today's private workflows. It eliminates the tedious manual setup and command-line barriers typical of legacy NAS hardware, letting users complete full-spectrum operations from system configuration and storage administration to app deployment entirely via natural language prompts.

"TOS 7 stands as the industry's first OS engineered for AI right at its core," a TerraMaster product lead stated. "When paired with the F4425 Pro, it empowers creators, small businesses and household users alike to own an intelligent, conversational data fortress that actively safeguards their critical files."

Blazing Core Performance: 8-Core Power & Up to 1010 MB/s Transfer Speeds
The F4425 Pro is equipped with Intel's 8-core N350 processor (ultra-low 7 W power draw), 16 GB DDR5 RAM, and dual 5GbE LAN ports. Link aggregation delivers combined throughput hitting 1010 MB/s—10x faster than standard gigabit Ethernet. It effortlessly handles native 4K/8K real-time editing, multi-user concurrent file access for dozens of users, and simultaneous operation of multiple virtual machines and Docker containers.

TOS 7: The World's First AI-Native NAS Operating System
Built around an AI-native design philosophy, TOS 7 features sweeping overhauls to its core system architecture:

• 500+ Modular RESTful APIs: For the first time, core low-level system interfaces are open for unrestricted access by AI agents and third-party developers.
• Full-Spectrum Natural Language Control: Supports multi-turn conversations, ambiguous prompts, and conditional automation rules (e.g., "Lock all shared folders immediately if ransomware is detected").
• On-Device Local AI Processing: Facial recognition for photos, automated file sorting and semantic analysis run entirely on the NAS hardware. No user data leaves the unit, eliminating privacy leakage risks entirely.
• Developer-First Ecosystem: A dedicated Skill Marketplace (coming soon) paired with a full suite of developer tooling lets third-party coders rapidly build, test and publish custom AI applications.

Four Game-Changing Features Redefine How NAS Works
1.Commands Through Conversation: OpenClaw AI Agent

Simply voice your requests—for example, "Create a 2 TB shared folder for the design team and set up weekly automatic snapshots"—and OpenClaw interprets and completes tasks automatically. No more memorizing commands or referencing manuals, putting a dedicated AI engineer at every user's disposal.

2.Pro-Grade 8-Core Architecture: Silent Powerhouse

Robust multitasking enables seamless concurrent workloads including 4K transcoding, virtual machine instances, and Docker orchestration with zero lag.

3.Proactive BBS Backup: Ultimate Data Safeguard

Built-in real-time ransomware protection, HyperLock immutable WORM technology, and automated 3-2-1-0 backup framework. Upon detecting suspicious file encryption, the system instantly executes a three-tier defense: lock target folders, quarantine relevant snapshots, and send instant alerts, shifting backup from reactive storage to proactive threat immunity.

4.Blazing 1010 MB/s Throughput: Unleash Creative Workflows

Bonded dual 5GbE connectivity delivers smooth direct editing of raw 4K/8K footage just like a local drive, eliminating tedious file transfers and proxy rendering entirely.

For Every User: Context-Aware Solutions

• Creative Studios: Editors can enable dual 5GbE optimization with a single voice command, supporting collaborative workflows with Final Cut Pro, Adobe Premiere Pro, and DaVinci Resolve.
• Growing Businesses: A single IT administrator can deploy permission templates, perform batch backups on over 50 computers, and monitor the overall security posture using the BBS central console—all via natural language.
• Developers & Geeks: Trigger a fully automated Git Pull → Build → Deploy CI/CD pipeline via OpenClaw, compatible with GitLab Runner and Jenkins, and supporting Ubuntu/Debian virtual machines.
• Modern Homes: Seamlessly back up mobile photo albums; AI automatically organizes content by time, faces, and locations, and supports Dolby Vision and HDR hardware transcoding to create a private home media library.

Scalable Storage and Ecosystem Expansion

• TRAID Flexible RAID: Supports mixing hard drives of different capacities; expand storage online without migrating data to maximize available space.
• TerraSync Cross-Platform Sync: Millisecond-level real-time synchronization across NAS, PC, Mac, and mobile devices, with version history traceability.
• Hybrid Cloud Storage Backup: Supports two-way synchronization with major cloud storage services such as OneDrive, Google Drive, and Dropbox.
• Docker & Virtual Machines: Pre-installed container and virtualization support for effortless expansion of unlimited applications.
