Product information

Description

The TerraMaster D2-320 is a versatile 2-bay desktop disk array designed to provide reliable external storage for home and home office environments. This diskless enclosure supports both 2.5-inch and 3.5-inch SATA HDDs and SSDs, offering a flexible solution for users who need to expand their storage capacity or manage data backups efficiently. With its high-speed USB 3.2 Gen2 interface, the device ensures rapid data transfer rates, making it suitable for demanding tasks such as media editing, large file storage, and system backups.

Advantages

The D2-320 stands out due to its high-performance USB 3.2 10Gbps connectivity, which allows for impressive read and write speeds when configured in RAID 0. The tool-free, push-lock drive tray design simplifies the installation and replacement of hard drives, allowing users to swap disks in seconds without needing extra tools. Furthermore, the device supports multiple RAID modes, including RAID 0, RAID 1, JBOD, and Single Disk, giving users the freedom to prioritize either performance or data redundancy based on their specific requirements.

The enclosure is engineered for longevity and quiet operation, featuring an intelligent temperature-controlled fan and an optimized internal structure that minimizes resonance and heat. It also includes an intelligent disk sleep function that synchronizes with the computer's operating system to save power and extend the lifespan of the installed drives. Additionally, the unit provides robust power supply protection to prevent damage from improper electrical input, ensuring that your data remains safe and secure.

Suitable for

Expanding storage capacity for home and home office computers
Creating RAID 0 or RAID 1 arrays for performance or data safety
Backing up critical files and system partitions using scheduled software
Expanding storage space for compatible TerraMaster NAS devices
High-speed data transfer for media professionals and content creators

This disk array may not be suitable for users requiring network-attached storage (NAS) functionality as a standalone device, as it is primarily a direct-attached storage (DAS) unit. It is also not intended for enterprise-grade server environments that require high-availability rackmount solutions or specialized fiber-channel connectivity.

To use the TerraMaster D2-320, simply insert your chosen 2.5-inch or 3.5-inch SATA drives into the tool-free trays and slide them into the enclosure until they lock into place. Connect the device to your computer using the provided USB Type-C cable. Once connected, you can configure your preferred RAID mode through your computer's disk management utility or the TerraMaster software. The device is compatible with various interfaces, including USB 3.0, 3.1, 3.2, and Thunderbolt 3 or 4 ports.

What to consider before purchase

Ensure your hard drives are compatible with the device by checking the manufacturer's compatibility list
Verify that your computer has a compatible USB or Thunderbolt port to achieve optimal speeds
Consider whether you need RAID 1 for data redundancy or RAID 0 for maximum speed
Check if your specific NAS model supports expansion via USB if you intend to use it for that purpose
