## Summary description

The jung D2-320 is a 2-bay desktop disk array designed for home and home office use. It accepts two 2.5" or 3.5" SATA HDD or SSD drives and provides a compact desktop chassis (119×154×222 mm) in black, weighing 1.3 kg. Suitable for storage expansion, backups and simple file sharing with easy installation and support for common SATA drives.

## Long description

TerraMaster D2-320 is a 2-bay external hard disk enclosure with a USB 3.2 Gen2 (10 Gbps) USB-C interface, designed for desktop storage expansion and fast data transfer. It accepts two 3.5" or 2.5" SATA drives (HDD or 2.5" SSD) and supports multiple RAID modes to address different storage and redundancy requirements. The enclosure features tool-free trays with a Push-lock mechanism, an included 0.8 m USB-C to USB-C cable, intelligent fan control, built-in power protection, and sleep support for energy saving.
Advantages
D2-320 provides high transfer speeds up to the limits of USB 3.2 Gen2; real-world read/write performance depends on the installed drives and selected RAID mode. It supports up to two drives with a single-drive capacity supported up to 22 TB, allowing a combined maximum raw capacity of 44 TB. The tool-free tray and Push-lock design enable quick and secure drive swaps without tools. The USB-C connection ensures compatibility with USB 3.0/3.1/3.2 hosts and Thunderbolt 3/4 ports. Adaptive disk sleep and a temperature-controlled low-noise fan reduce power consumption and operating noise. The external power adapter includes protection to help prevent damage from improper power sources.

How to use
Install one or two compatible SATA drives into the tool-free trays and insert the trays into the enclosure until the Push-lock secures them. Connect the D2-320 to your host using the supplied USB-C cable; the enclosure is compatible with USB 3.0/3.1/3.2 and Thunderbolt 3/4 host ports. Configure the desired RAID mode using the host operating system or compatible management tools before formatting the drives. Enable disk sleep in the host OS if you want the enclosure to follow the computer's sleep behavior. For scheduled Windows backups, install the TPC Backupper client, connect the D2-320 and create a backup task (supports incremental and differential backups; compatible with Windows 8/8.1/10/11).
Recommendations
Verify drive compatibility with TerraMaster's compatibility list before purchase. Use the supplied or a proper external power adapter and connect via a USB-C or Thunderbolt-capable port to achieve optimal performance. When frequently swapping drives, ensure the Push-lock is fully engaged to avoid accidental disconnection. For NAS expansion features, update TerraMaster NAS to TOS 5.1 or later.
