TERRAMASTER D6-320 External Hard Drive Enclosure — USB 3.2 Gen2 10Gbps, Diskless

Designed for creators, professionals, and power users who demand fast, flexible, and scalable storage, the D6-320 is a six-bay DAS that lets you mix and match up to six SATA drives without locking you into a RAID. It’s the practical backbone for fast backups, on‑set transfers, and expansive media libraries.

Blazing-fast performance with flexible storage

• USB 3.2 Gen2 interface delivers up to 10Gbps bandwidth for rapid data transfers.
• Real-world speeds: up to 1,030 MB/s read/write across supported drives.
• Single-drive performance: a SATA III HDD or SSD (e.g., 1TB HDD) can reach about 510 MB/s read speed.
• Diskless by design — install your own HDDs or SSDs to build a custom storage array exactly the capacity you need.

Massive, scalable storage you control

• Supports up to six drives in total, with 3.5" and 2.5" SATA HDDs and 2.5" SATA SSDs.
• Per-drive capacity up to 22TB, for a total potential of up to 132TB when fully populated (22TB × 6).
• Note: does not support drive arrays; each bay operates as an individual disk.

Plug-and-play, broad compatibility

• Includes a 1-meter USB Type-C to Type-A cable for quick setup — plug in and go, no drivers required.
• Backward and forward compatibility with USB 3.0/3.1/3.2 and Thunderbolt 3/4 interfaces.
• To connect to a USB-C computer port, you’ll need a separate USB Type-C to Type-C cable (sold separately).

Smart cooling, quiet operation, and longevity

• Temperature-controlled cooling fan adjusts speed according to drive temperature for consistent performance.
• Optimized internal airflow and is designed to minimize heat buildup, noise, and resonance during heavy use.
• Hot-swappable design lets you replace disks without powering down, supporting uninterrupted workflows.
• Built-in sleep functionality aligns with your PC’s sleep mode to reduce power consumption and extend disk life.

NAS expansion and future-proofing

• Can expand TerraMaster NAS storage via USB with proper adaptation.
• Requires TerraMaster NAS with TOS 5.1 or later to create arrays and storage pools on the D6-320.

What’s included

• 1-meter USB Type-C to USB Type-A cable

Whether you’re editing 4K footage, managing a growing media library, or backing up large archives, the TERRAMASTER D6-320 offers the speed, capacity, and flexibility needed to keep your workflow flowing smoothly—without compromising on control or reliability.
