Description
TerraMaster D2-320 Overview
The D2-320 4-Bay USB 3.2 Gen 2 RAID Enclosure from TerraMaster can function as a stand-alone storage enclosure, or be used an expansion enclosure for TerraMaster NAS devices running TOS 5.1 or above. Built with two SATA drive bays that can handle 2.5 or 3.5" hard drives and SSDs, the D2-320 delivers data transfers of up to 1075 MB/s and write speeds of up to 956 MB/s when equipped with two SSDs configured as RAID 0. It connects to your host Windows, Mac, Linux, or TOS system using a 10 Gb/s USB-C 3.2 Gen 2 (3.1 Gen 2/3.1) port that is compatible with USB 3.2 Gen 1 (USB 3.1 Gen 1/3.0), Thunderbolt 3, or Thunderbolt 4. The D2-320 may be configured in RAID 0, 1, JBOD, or single using a switch on the back.
Each drive bay allows for user-friendly and tool-free installation. Plug-and-play connectivity means that no additional drivers are required for use, while an intelligent 80mm cooling fan operates based on system temperature, ensuring that the drives operate within their optimal range.
Please note that the D2-320 does not currently support individual drives larger than 22TB.
High Speed
With the USB 3.2 Gen 2 protocol, the D2-320 provides a 10 Gb/s data transmission bandwidth, with the actual read/write speeds of up to 521 MB/s when two hard drives are installed and read speeds of up to 1075 MB/s when two SSDs are used in RAID 0.
Super Large Storage Space
The D2-320 supports up to two hard drives and a maximum drive capacity of 22TB (compatibility with larger hard drives has not yet been verified), providing users with up to 44TB of storage (2 x 22TB).
Compatible with a Wide Array of Drives
The D2-320 is compatible with various hard disks, such as 3.5 and 2.5" SATA hard disks, and 2.5" SATA SSDs. Please note that using incompatible drives may cause your device to become disconnected, with low transfer speeds and drive recognition failures. Before you purchase any drives, please be sure to check TerraMaster's drive compatibility list.
Multiple RAID Modes
Supports multiple RAID modes: RAID 0, 1, JBOD, and Single Disk. Professionals can choose one or more according to their application scenarios.
Hot Swappable Drives
The D2-320 features a tool-free hard drive tray design that allows for easy installation and removal of hard drives without the need for any tools. Furthermore, the D2-320 incorporates a push-lock design, which automatically locks the hard drive tray when you insert a drive, preventing it from falling out or disconnecting. As a result, installing a hard drive takes less than 10 seconds, making it convenient for users who frequently swap hard drives to exchange data.
Compatible USB-C Interface
The D2-320 is equipped with a USB-C interface and a 3.3' USB-C to USB-C cable. It may also be used with a variety of computer interfaces, including Thunderbolt 4, Thunderbolt 3, and USB 3.2 Gen 1 (3.1 Gen 1 / 3.0).
Expand Your NAS' Storage Space
The D2-320 can be connected to the USB interface of a TerraMaster NAS after special adaptation and adjustment. Creating arrays and storage pools on D2-320 with TerraMaster TOS could expand the storage space of your NAS.
Note: This function works only on TerraMaster NAS running TOS 5.1 or above.

Intelligent Disk Sleep
The D2-320 supports sleep functionality, which can follow the computer OS to sleep, effectively reducing the working duration, and power consumption of the hard disk and extending its service life.
Safer
To prevent equipment and drives from being damaged by use of an improper power supply, the D2-320 adopts power supply protection. In the case of an improperly connected power supply, the device will enable automatic protection to prevent itself and the hard disk from damage.
Very Quiet
The D2-320 adopts an intelligent temperature controlled and low-noise fan that adjusts its speed automatically based on the temperature of the hard disk to ensure it works at an optimal operating temperature. Furthermore, the internal structure of the device is specially optimized, which not only effectively increases the internal air pressure and reduces the working temperature of the hard disk, but also greatly reduces the resonance between device components and the hard disk. With this feature, the D2-320 can maintain satisfactory low noise, even under a full-load working environment.
