Key Features

• High‑Speed USB 3.2 Gen2 Interface

Fast data transfers — The D6‑320 uses USB 3.2 Gen2 technology, offering up to 10 Gbps connection speeds. This means large files move much faster between your computer and the enclosure compared with older USB standards.

• Six‑Bay Large Storage Capacity

Huge storage potential — It supports up to six SATA drives (3.5″ HDD or 2.5″ HDD/SSD), allowing you to combine many high‑capacity drives for a total storage space that can reach hundreds of terabytes depending on drive size.

• Plug‑and‑Play Compatibility

Easy setup — No special drivers are needed. Simply connect the enclosure to a Windows, macOS, or Linux system and start using it. This makes it convenient for both casual and professional users.

• Hot‑Swappable Drive Bays

Swap without shutting down — You can insert or remove drives while the enclosure is powered on, which is ideal for quickly replacing drives or adding new ones without interrupting work.

• Intelligent Cooling & Noise Control

Auto‑adjusting fan system — Smart fans monitor drive temperature and adjust speed automatically, keeping drives cool while reducing unnecessary noise during normal operation. This helps prolong drive life and keeps the unit quiet.

• Power‑on Recovery & Safeguards

Protection against power issues — The unit can remember its last power state and automatically restart after an unexpected power loss, which is useful if it’s part of a server or storage setup. It also includes built‑in power protection to guard drives against improper power supply conditions.

• NAS Expansion Support

Optional NAS use — When paired with a compatible TerraMaster NAS and the right firmware, you can use the enclosure to expand NAS storage, treating drives or pools as additional space for network storage.

Applications

• High‑Capacity External Storage

Use the D6‑320 as a large external drive bank for storing massive files, media libraries, backups, and archives. With support for up to six SATA drives, it lets you keep hundreds of terabytes of data in one place without needing a NAS.

• Backup Destination

It’s ideal as a target for scheduled backups from Windows, macOS, or Linux computers. You can pair it with backup software (e.g., TerraMaster’s TPC Backupper on Windows) to protect important documents, photos, projects, or system images.

• NAS Storage Expansion

When connected to a TerraMaster NAS (running TOS 5.1 or later), you can extend NAS storage by using the drives in the D6‑320:

1. Add them to a storage pool or array as additional volumes.

2. Use each disk as a separate storage resource for different data sets.

• Media & Creative Work Storage

Content creators, videographers, and photographers can use it as a central repository for large media files (e.g., raw video footage, project files, libraries), making it easier to manage and access across multiple editing sessions.

• Direct Attached Storage for Workstations

Connect the enclosure directly to a PC or workstation via USB 3.2 Gen2 for high‑speed local storage — useful for editing, data processing, CAD, and other tasks that need fast, high‑capacity storage without network access.

• Drive Migration & Rotation

Because the bays are hot‑swappable, it works well in environments where drives need to be swapped or rotated regularly, such as moving large datasets between systems or archiving old drives while adding fresh ones.

• Cross‑Platform Storage Sharing

It’s plug‑and‑play compatible with Windows, macOS, and Linux, making it a versatile storage hub that can be used across different machines or operating systems without complex setup.
