D4-320

TerraMaster

The D4-320 4-Bay USB 3.2 Gen 2 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 four SATA drive bays that can handle 2.5 or 3.5" hard drives and SSDs, the D4-320 delivers data transfers of up to 1016 MB/s and write speeds of up to 960 MB/s when equipped with four SSDs. 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. Please note that the D4-320 may not be configured as a RAID without the use of third-party software.Each drive bay is hot swappable and allows for tool-free installation. Plug-and-play connectivity means that no additional drivers are required for use, while an intelligent 120mm cooling fan operates based on system temperature, ensuring that the drives operate within their optimal range.Please note that the D4-320 does not currently support individual drives larger than 30TB.New Upgrade, Refreshed Experience As an upgrade to the D4-300, the D4-320 offers several revolutionary changes while maintaining affordability. Its new design concept offers a stylish and minimalist appearance that is more aesthetically pleasing, while its underlying technology offers a qualitative leap in terms of performance, allowing users to access outstanding functionality.Speed Boost The D4-320 utilizes the USB 3.2 Gen 2 protocol to achieve a data transfer speeds of up to 10 Gb/s, which is twice the speed of the D4-300, which runs at 5 Gb/s. When equipped with four hard drives, the actual read/write speed can thus be measured at up to 1016 MB/s (combined read/write with four WD Red 8TB SSDs). Even with just one 1TB WD Red SSD installed, the read speed reaches 510 MB/s. Thus, whether using multiple hard drives operating in parallel or ensuring the efficient operation of a single hard drive, the D4-320 demonstrates exceptional performance.Convenient Swapping of Hard Drives The hard drive bracket introduced by the D4-320 offers tool-free installation and removal of hard drives, making the whole process simple by eliminating the need for cumbersome tools. In addition, the push-lock design created by TerraMaster allows gentle pressure to be used to ensure a secure lock, effectively preventing detachment or disconnection. This not only ensures stable data transmission, but also enhances the efficiency of hard drive replacement. Installing a hard drive thus takes only a few seconds, providing additional convenience for users who frequently swap hard drives.Better Heat Dissipation The D4-320 is equipped with an intelligent, temperature-controlled, low-noise fan. The fan speed is constantly adjusted based on hard drive temperature, ensuring that the hard drives always operate within their optimal temperature range. In addition, the carefully designed internal structure of the device effectively enhances internal air pressure, further reducing the working temperature of the hard drives and significantly minimizing any resonance between the device components and hard drives. Even under a full load, the D4-320 thus maintains excellent low-noise performance, providing a quiet and comfortable working environment.Reduced Noise: up to 50% Quieter As desktop products are typically positioned close to users, their noise levels must be subject to strict requirements. During read/write processes using mechanical hard drives, the high-speed rotation of disks and heads can generate excess vibrations and noticeable noise, which may resonate within the product enclosure, further amplifying the overall sound level. To address this, engineers at TerraMaster have not only implemented additional vibration damping measures in this new generation of products, but also have carefully designed numerous specialized sound absorbing panels. The resulting designs help to significantly reduce nois
