TerraMaster has handed control of the NAS to a plain sentence. TOS 7 is the seventh generation of the system, called by its maker the first AI native NAS operating system, and the x86 release reached 7.0.1341 on 13 October 2026.

How far one sentence actually gets

Building a storage pool, setting permissions and installing a container used to mean clicking down through menus until a tutorial read three times still left the switch unfound. TOS 7 reorganises the abilities of the system into a set of standardised interfaces, more than five hundred by the official count, and adds a command line and a skill pack that the built in agent can call. Typing into a web page, a phone or a chat window all work, and the instruction becomes a series of actions inside the system.

The official line is that nine tenths of NAS operations can be done in natural language, including storage management, system configuration and service deployment, the parts that used to wind the most. The agent runs on the device, so file retrieval, document parsing and content classification happen inside the machine and are not uploaded. Scheduled jobs and conditional triggers can be described the same way, whether that is backing up a directory every night at two or investigating by itself when a drive reports an error.

Desktop and file manager both rebuilt

The visual language changed this generation, nine tenths of the icons redrawn and a new set of wallpapers. Desktop icons can be dragged and snap into line near a grid; the navigation bar is customisable; a message centre on the right collects system notices and task progress. It feels more like a desktop environment than a web console.

The file manager was taken out and rebuilt on its own, with tabs and a split view as the point: one directory on the left, another on the right, so moving across directories needs no backtracking. The maker claims a sixty percent gain in efficiency for operations across and between directories. Recycle bins scattered over volumes and folders are merged into one, so a mistaken delete is recovered in a single place. ISO images mount themselves, which removes a manual step when installing a system or building a virtual environment.

Search changed engines

Global search is the gap this generation fills. A home grown inverted index, with kernel level awareness of file changes and an asynchronous cache, is quoted at a hundred and twenty percent better indexing and precision and ten times the query speed. In felt terms: a million files answered within ten seconds, ten million in about half a minute. The scope is not file names alone, since applications, settings and the content inside files are indexed too.

Permissions and collaboration move toward business use

The permission system grows from three kinds to thirteen, adding custom entries beyond basic read and write, so an administrator can set policy by role and by directory at a finer grain, and access across protocols falls under the same rules. For teamwork, documents in common formats open in the browser with several people editing at once, and the file never leaves the device. The app centre adds ten categories, a recommended Docker image starts a common scenario in one step, and application logs can be traced separately.

Network control goes to three dimensions: bandwidth assigned by port, by service and by user. Remote access runs through the maker's multi node service, and the phone client can read device state and handle alerts.

Developer mode opens the door

TOS 7 hands out full root for the first time and connects the Ubuntu repositories, so anything apt can install can be installed. The system also carries a KVM based virtualisation centre where Windows and Linux machines deploy in one step, with containers and virtual machines living on the same box. For anyone who likes to tinker, this NAS amounts to a Linux host that can be reinstalled at will.

Where the version numbers stand

TOS 7 went out worldwide on 23 June 2026, ARM models followed in August, and the notes state that the ARM build carries no AI features and cannot install third party agents. On x86 the pace is weekly, and 7.0.1341 from 13 October is a defect release: it fixes updates failing when an application version carries a hyphen, loose validation of interface paths, and hidden files missed when selecting all and deleting.

A four bay machine, the F4-425 Pro, went on sale at the same time, sharing the launch material with TOS 7. Anyone holding older hardware should check the support list in the update thread on the official forum: the 424 and 425 series and the F4-422 through F5-422 batch are on it, and some U and T models can upgrade too. A few machines with the system on an M.2 drive need the boot order in the BIOS adjusted first, following the guidance in that thread.

Turning a NAS into a machine that understands plain speech tests more than the model; it tests whether the system is willing to expose its lower interfaces. TOS 7 chose to expose them, and the price is thinking again about which directories are safe to hand over.
