TerraMaster was established in 2010 with a focus on developing professional storage solutions. The company’s initial products were NAS systems aimed at businesses requiring centralized data storage and backup. [1]

Over time, TerraMaster expanded into:

• Consumer NAS

• Professional video editing storage

• Thunderbolt DAS

• Rackmount enterprise storage

• SSD-based storage systems

• Hybrid RAID technologies

• Backup software

• Cloud synchronization solutions

Today, TerraMaster develops both its hardware and software ecosystem in-house, including the TOS operating system and proprietary storage technologies. [1]

1. NAS (Network Attached Storage)

TerraMaster is primarily recognized for its NAS products.

NAS devices connect to a network rather than directly to a computer, allowing multiple users to:

• Store files

• Share folders

• Create backups

• Stream media

• Host private cloud services

• Run Docker containers

• Virtualize operating systems

• Manage surveillance systems

Popular NAS series include:

• F2 Series

• F4 Series

• F5 Series

• F8 SSD Series

• U Series (Rackmount)

2. DAS (Direct Attached Storage)

Unlike NAS, DAS devices connect directly via:

• USB-C

• USB4

• Thunderbolt 3

• Thunderbolt 5 (newer models)

They are widely used by:

• Video editors

• Photographers

• Music producers

• Content creators

Popular DAS families include:

• D2

• D4

• D5

• D8

• D16

• D1 SSD Series

3. RAID Storage

Many TerraMaster products support RAID configurations, including:

• RAID 0

• RAID 1

• RAID 5

• RAID 6

• RAID 10

• JBOD

• Single Disk Mode

In addition, TerraMaster offers its own proprietary RAID technology called TRAID.

TOS (TerraMaster Operating System) powers the company’s NAS devices.

Key features include:

• Web-based management interface

• File sharing

• User permissions

• Docker support

• Virtual Machine Manager

• Snapshot protection

• AI-powered photo management

• Encryption

• Btrfs filesystem support (on supported models)

Recent versions have added enhanced ransomware protection, developer features, and broader application compatibility. [1]

TRAID / TRAID+

TRAID (TerraMaster RAID) is TerraMaster’s flexible RAID implementation.

Features include:

• Mixed-capacity drive support

• Online expansion

• Automatic storage optimization

• Simplified migration

TerraMaster competes in the storage market with brands such as:

• Synology

• QNAP

• Asustor

• UGREEN

Compared with these competitors, TerraMaster is generally known for:

• Competitive pricing

• Strong hardware specifications for the cost

• Broad support for open technologies (Docker, virtualization, Linux-based tools)

• Flexibility for enthusiasts and home labs

Independent reviewers have praised the value and hardware of many TerraMaster models, while also noting that the software ecosystem has historically been less mature than some long-established competitors, though recent TOS releases have expanded features and security. [2]

TerraMaster distributes products through official online channels and regional partners in North America, Europe, Asia, Australia, and Latin America. Its products are available through its official store as well as major electronics retailers and marketplaces in many countries. [1]

TerraMaster has evolved from a NAS hardware manufacturer into a broader storage platform provider, combining in-house hardware, the TOS operating system, backup software, RAID technologies, and high-speed DAS solutions. Its products target everyone from home users to professional creators and businesses, with an emphasis on balancing performance, flexibility, and cost. [1]
