High speed
Adopting USB3.2 Gen2 protocol, D2-320 provides 10Gbps data transmission bandwidth, the actual read/write speed can be up to 521MB/s when 2 hard drives are installed (Seagate Eoxs 22TB X2 RAID 0); by installing two hard drives, the reading speed can reach 1075 MB/s (SAMSUNG 870QVO 1TB SSD X2 RAID 0).

Super-large storage space
The D2-320 supports up to 2 hard drives and a maximum drive capacity of 22 TB (compatibility with larger hard drives has not yet been confirmed), giving users up to 44 TB of storage space (22 TB x 2).

Compatible with different types of hard drives
D2-320 is compatible with various hard drives such as 3.5 inch and 2.5 inch SATA hard drives and 2.5 inch SATA SSD. Note: using an incompatible hard drive may cause the device to disconnect, slow speed, and fail to recognize the hard drive. Before purchasing, please check the compatibility list of TerraMaster hard drives.

Multiple RAID modes
It supports multiple RAID modes: RAID 0, RAID 1, JBOD and Single Disk. Professionals can choose one or more according to application scenarios.

Convenient replacement of hard drives
The D2-320 features a tool-less hard drive tray design that allows easy, tool-free installation and removal of hard drives. The D2-320 also features TerraMaster's brand new, unique Push-lock design, which automatically locks the hard drive tray when the hard drive is inserted, preventing the hard drive from falling out or disconnecting. As a result, hard drive installation takes less than 10 seconds, which is a great convenience for users who frequently change hard drives for data exchange.

Highly compatible interface
D2-320 has a USB Type-C interface and a USB-C to Type-C cable (0.8 meters long) and can be compatible with a variety of computer interfaces: USB 3.0/USB 3.1/USB 3.2/Thunderbolt 3/Thunderbolt 4.

Expanding NAS storage space
The D2-320 can be connected to the USB port of the TerraMaster NAS after special adaptation and adjustment. Using TerraMaster TOS, you can create arrays and storage pools on the D2-320 to expand the storage space of your NAS. Note: This feature only works on TerraMaster NAS with TOS 5.1 or higher.

Smart disk sleep mode
The D2-320 supports the sleep function, which can follow the computer's operating system into sleep mode, effectively reducing the operating time and power consumption of the hard disk and extending its life.

It's safer
In order to prevent the equipment and hard disk from being damaged due to the use of an inappropriate power supply, the D2-320 adopts power supply protection. If the wrong power supply is connected, the device will activate automatic protection to protect itself and the hard drive from damage.

Very quiet
The D2-320 uses an intelligent temperature-controlled and low-noise fan that automatically adjusts its speed based on the temperature of the hard drive to keep the hard drive at the best operating temperature. Furthermore, the internal structure of the device is specially optimized, which not only effectively increases the internal air pressure and reduces the operating temperature of the hard disk, but also greatly reduces the resonance between the device components and the hard disk. maintain a noise level.
