1. Upgraded kernel 

The TOS 5.1 kernel has been updated from 4.19 to 5.15. Compared to the previous generation kernel, TOS 5.1 Beta optimized EXT4/Btrfs/NTFs file systems and SMB3 file server, used ext4/f2fs/ubifs file system encryption in the encryption API, enabled Apple M1 SoC functionality under Linux and added USB 4 interface support, which greatly improved the performance and security of file system.

2. 4K hardware decoding   

The new hardware decoding driver for Intel Jasper Lake GPU is added, which will significantly improve 4K video hardware decoding capability for TerraMaster NAS.

3. Storage pool expansion via USB   

By connecting TerraMaster USB disk array, users can easily expand the storage space of the storage pool for TNAS. It supports TRAID/RAID 0/RAID 1/RAID 5/RAID 6 array mode and provide 10Gb storage bandwidth. Compared with eSATA or mini SAS expansion enclosures, TerraMaster USB expansion enclosures are more economical and more convenient.

4. Hyper Cache   

TerraMaster Hyper Cache is TerraMaster unique SSD cache acceleration tool. Hyper Cache can provide up to 3 cache modes to choose from to suit different usage needs, and can also create disk arrays for SSDs to increase cache speed and security. Such configuration delivers high-speed storage that’s ideal for video editing.

5. Categorized notifications    

TOS 5.1 Beta optimizes system messages and divides message notifications into four levels: information, success, error, and warning. Each level of messages is marked with a more eye-catching symbol of different colors. User can always keep track of any abnormalities in the system and ensure the security of the system and data.

6. USB storage management     

TOS 5.1 fully optimizes the mounting of USB partitions. The system will record the path of the last mounted USB partition. When re-mounting next time, the original path will be allocated first to provide more storage space for the use and backup of USB.

7. Optimized Docker Manager      

TerraMaster launches updated version of Docker Manager and updates the Docker engine to 20.10.17 version. The optimized interface brings it in line with users’ aesthetics and usage habits. Container deployment is more flexible and TerraMaster NAS utilization is optimized.

8. Better AI computing performance      

TOS 5.1 replaced the more powerful Intel OpenVINO AI computing engine, combined with the new Terra Photos application, the intelligent photo recognition efficiency increased by 30%. Terra Photo is designed for home users and photography enthusiasts to manage photo storage, share and access photos from anywhere.


The TOS 5.1 Beta version released this time is only applicable to some TNAS models in X.86 series (221 series, 421 series, 422 series, 223 series, 423 series).
