TOS 7 Beta: Simply Powerful. Powerfully Simple.

Our digital lives grow faster than we notice—photos from years past, videos worth keeping, work we’re proud of, ideas still taking shape. Over time, these files stop feeling like “data” and become something more personal: the record of who we are and what we create. And with that comes the need for a place where all of it can truly belong.

With TOS 7, TerraMaster set out to build a system worthy of that responsibility—powerful for professionals, yet calm and approachable for everyday use. After two years of development, over fifty new features, and more than a thousand refinements, it all culminates in TOS 7 Beta, available for public testing starting December 15. This is an OS that’s not just faster or more secure, but more thoughtful—a simpler, more human way to live and create with your data. Join us in shaping the future of storage.

A First Impression That Stays With You

Sign in to TOS 7, and you’re greeted by a quiet sense of order. The redesigned interface balances modern clarity with intuitive structure. A navigation bar that adapts to your habits. A desktop where everything moves fluidly with simple drag and drop. A message center that appears only when necessary.

Every element is designed to help you focus on your work—not the system beneath it.

And beneath that refined surface lies the new Linux 6.12.41 kernel, driving a leap in responsiveness. Apps launch faster. Searches feel immediate. The entire system operates with a confidence and stability you can feel, even if you never notice the engineering behind it.

Efficiency That Feels Designed Around You

True efficiency isn’t about shortcuts—it’s about understanding how people work.

For creators, the new global search—up to 10× faster—makes finding inspiration almost instant, even within massive media libraries. Online Office editing allows teams to update Word, Excel, and PowerPoint files directly in the browser, keeping collaboration seamless.

For managers and small businesses, 13 levels of granular permissions and a clear, visual storage dashboard turn complex administration into something almost effortless. Deploying users, managing access, or expanding storage takes minutes rather than hours.

For families and individuals, the enhanced backup suite and desktop-like File Manager—featuring tabs, split view, and one-click mounting—keep precious memories both safe and easy to reach.

TOS 7 is built to minimize the time you spend managing, so you can maximize the time spent creating, working, and living.

Built for Curiosity. Built for Growth.

Some users want simplicity. Others want freedom. TOS 7 offers both.

Developer Mode unlocks full root access and direct integration with the Ubuntu software repository, giving advanced users the freedom to install languages, tools, or services without restrictions.

The new Virtual Machine Center allows you to run complete operating systems directly on your NAS—perfect for testing, experimenting, learning, or building isolated environments.

A refreshed Application Center brings a richer collection of Docker-based services, many of which can be deployed with a single click.

Whether you're building a home media server, developing software, or exploring new ideas, TOS 7 grows naturally with your ambitions.

Connection That Follows You Anywhere

No matter where you are, your digital world stays close.

The rebuilt TNAS.online remote access service delivers stable, secure, high-speed connectivity across the globe—without complex configuration or router settings.

And the redesigned TNAS.mobile app brings effortless control to your phone. Check storage, browse files, manage users, back up photos, or share links with a single tap.

Your NAS feels as close as the device in your hand.

Powerful, Yet Deeply Understanding

TOS 7, together with new TerraMaster devices like the F4-425 Plus, represents our renewed vision for what a NAS should be. It should be a dependable foundation for your work. A safe and welcoming home for your memories. A system powerful enough to support your ambitions, yet refined enough to disappear into the background when you simply want to enjoy your life.

Simply powerful. Powerfully simple.

This is the experience your data deserves.
