TOS 6 Operating System Key Features

The Latest Linux Kernel
The kernel of TOS 6 is based on the latest Linux Kernel 6.1 LTS, which introduces MG-LRU to enhance system performance, significantly improves the performance of the btrfs file system, adds erofs for cross-file system data sharing, prepares for support of the Intel Meteor Lake 5nm chip, merges the Kernel Memory Sanitizer (KMSAN) for enhanced memory management, achieves faster Intel memory error decoding via the EDAC driver, introduces support for the Maple Tree data structure, and implements new security controls on the ability to create user namespaces.

Significantly Improve System Response Speed
The system is no longer automatically installed on every disk, but users are now allowed to specify the installation location. Users can select up to four hard drives or SSDs as system disks, enabling them to install the system on faster storage devices, thereby enhancing system response speed, application data loading speed, and data commit efficiency.

New Desktop, Focused and Simple
The new desktop design reduces the distraction from complex pages, allowing users to focus more on the contents. Desktop icons were removed to create a clean background free from clutter, with all applications now displayed in the navigation bar for easier switching between menus.

New System Dashboard
TOS 6 brings an improved system dashboard with a new layout that provides users with a high degree of custom functionality. Users can freely customize what content modules are displayed and rearrange their order simply by dragging. This makes the dashboard much more attuned to users’ habits.

The Industry’s First NAS File Management Tab
TOS 6 comes with the industry’s first NAS file management tab. By using the tab mode, users can easily move, copy and paste files between different file directories without the need to open a new page, greatly increasing the convenience and user-friendliness of file management.

13 Advanced Permissions Management Strategies
TOS 6 brings an impressive leap in the management of permissions. Except for the traditional Deny, Read Only, and Read/Write permissions, TOS 6 introduces advanced ACL permission management, allowing administrators to customize access to shared folders as needed. In addition, users’ administrative, read, and write permissions for folders are subdivided into 13 types, enabling access control to be refined for more complex file requirements in the enterprise environment.

Security Level Enhanced by 500%
SPC (Security and Privacy Control) is the latest unique security control function developed by TerraMaster. The access permissions of TOS’s executable programs and applications to network and storage spaces are strictly controlled, requiring user authorization before use.This prevents the TOSsystem from being attacked by ransom-ware or malicious hacker code, making TOS 6 five times more secure than the previous system.

Hyper-Lock WORM Dual Modes
TOS 6 adds Compliance and Enterprise Modes to the Hyper-Lock WORM file system to give users greater flexibility. In Compliance mode, once data is written, it cannot be modified or deleted to meet regulatory requirements for storing sensitive data. In Enterprise mode, it allows enterprise
IT administrators to customize how long the data is locked.

Hot Swapping of Data Disk Avoids Formatting
With TOS 6’s excellent hard disk recognition function, neither Startup/Shutdown nor hard disk reformatting is needed. Users can hot swap the hard disk of any supported file system at any time, and directly access data in that hard disk without reformatting.

The Perfect Integration of F4-424 Pro and TOS 6
The industry-leading 4bay NAS F4-424 Pro product perfectly supports the latest TOS 6 operating system, bringing users the ultimate storage and operation experience. F4-424 Pro has become the first choice of many professional users and storage enthusiasts due to its powerful hardware configuration and excellent performance.
