Key Features

1. Powerful Hardware for Business Workloads

• Intel Core i5‑9400 6‑core CPU: Delivers strong processing power for heavy tasks like virtualization, large file transfers, and database services.

• Expandable RAM: Starts with 8 GB DDR4 and can be upgraded up to 128 GB, enabling smoother multitasking and improved caching performance.

2. Scalable & Flexible Storage

• 8 drive bays: Supports both 3.5″ HDDs and 2.5″ SSDs for versatile storage configurations.

• M.2 NVMe slot: Lets you add an SSD for cache acceleration, improving responsiveness and I/O speeds.

• Multiple RAID modes: Offers RAID 0, 1, 5, 6, 10, JBOD, and SINGLE for balancing performance and data protection.

3. High Network Performance & Reliability

• 4 × Gigabit Ethernet ports: Enables link aggregation, which combines multiple network connections to boost throughput and provide failover protection if one link drops.

• PCIe expansion slots: You can add 10 GbE network cards or advanced RAID controllers to future‑proof connectivity.

4. Advanced File System & Data Protection

• Support for Btrfs filesystem: Offers modern features like snapshots (point‑in‑time copies), rollback, and self‑healing mechanisms to reduce the risk of data corruption.

• Comprehensive backup methods: Includes support for Apple Time Machine, USB backups, and Rsync remote backups to protect data from loss.

5. Strong Security & Access Management

• User & rights management: Supports RBAC (role‑based access control) and Windows ACLs to control who can see or modify files.

• Security features: Includes password login, HTTPS access, firewall controls, and optional AES‑256 disk encryption to safeguard data even if drives are removed or stolen.

6. Rich Software Ecosystem

• TOS Enterprise OS: TerraMaster’s operating system provides a graphical interface for easy management of storage, users, and services.

• Professional applications: Run file servers, web/VPN/DHCP/DNS servers, database services, and more — making one NAS capable of handling many business functions.

• Remote access: Supports remote connectivity so you can manage and access files securely outside your local network.

7. File Sharing & Protocol Support

• Wide protocol support: Shares files across networks using SMB/CIFS, AFP, NFS, iSCSI, and FTP, making it compatible with Windows, macOS, Linux and mixed environments.
