New Upgrade, Refreshed Experience

As an upgrade to the classic D4-300, the D4-320 hard drive enclosure 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.

Enhanced Speed and Performance:

Utilizing USB 3.2 Gen2 protocol, the D4-320 USB storage achieves lightning-fast data transfer speeds of up to 10 Gbps, doubling the speed of its predecessor (D4-300). Whether handling multiple hard drives concurrently or a single drive, the D4-320 consistently delivers exceptional performance, reaching read/write speeds of up to 1,016 MB/s (combined read/write with SATA III HDDs x 4). Even with just one SSD installed, the read speed effortlessly reaches 510 MB/s (SATA III 1TB SSD). 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.

Flexible and Compatible Connectivity:

The D4-320 direct attached storage boasts strong interface compatibility with its USB Type-C interface, providing seamless connections to various computer interfaces, including USB 3.0, USB 3.1, USB 3.2, Thunderbolt 3, and Thunderbolt 4. Its hot-swappable support and driverless, plug-and-play functionality make it a versatile and user-friendly storage solution, compatible with different operating systems and devices.

Convenient and Efficient Hard Drive Management:

The D4-320 HDD enclosure introduces a revolutionary tool-free hard drive bracket with a Push-lock design, allowing quick and secure installation without the need for tools. This innovative design ensures stable data transmission, greatly enhancing the efficiency of hard drive replacement. Swapping hard drives becomes a seamless process, providing added convenience for users who frequently switch drives. Additionally, the D4-320 is exceptionally quiet during its operation, thanks to its specialized sound-absorbing panels and vibration damping, which reduce noise levels by up to 50% compared to the previous generation, dropping below 21 dB(A) in standby mode for a remarkably quiet user environment.

Versatile Storage Expansion:

With support for up to four hard drives, each with a maximum capacity of 22TB, the D4-320 offers a powerful storage expansion of up to 88TB. Based on careful adaptation and optimization by the professional team at TerraMaster, the D4-320 offers seamless connection to the USB interface of TerraMaster NAS. Leveraging the powerful TOS system developed by TerraMaster, users can easily create arrays and storage pools on the D4-320, effectively expanding the storage space of their NAS to meet growing demands for data. This feature is only applicable to TerraMaster NAS devices running TOS 5.1 or above. Based on this innovative feature, the D4-320 provides users with a more flexible and diverse storage expansion solution.
