TerraMaster, a trusted leader in innovative storage solutions, proudly introduces the D4-320U, a compact 1U 4-bay direct-attached storage (DAS) enclosure
designed for small offices, home users, and IT environments. Combining a space-saving rackmount design, massive 88 TB storage capacity, and lightning-fast 10 Gbps USB 3.2 Gen 2 performance, the D4-320U delivers unmatched versatility and efficiency for modern data demands.
D4-320U Key Features
Compact Design for Seamless Deployment
The D4-320U redefines convenience with its miniaturized 1U rackmount form factor. Measuring just 241 mm (9.49 inches) in depth, 50% shorter than traditional chassis and weighing 3.2 kg, this sleek enclosure fits effortlessly into standard server racks without the need for rails, simplifying installation. Its space-efficient design maximizes room utilization in data centers, storage closets, stairwells, or offices, making it an ideal choice for small businesses and SOHO users seeking centralized storage solutions.
Massive 88 TB Storage Capacity
With support for up to four drives, the D4-320U offers a staggering maximum capacity of 88 TB (using 22 TB drives, with larger capacities pending compatibility verification). Operating in single-disk mode by default, users can leverage third-party software RAID tools to create arrays, catering to extensive storage needs from media libraries to enterprise backups.
High-Speed Data Transfer at 10 Gbps
Equipped with the USB 3.2 Gen 2 protocol, the D4-320U achieves a blazing 10 Gbps bandwidth. When paired with four 8 TB WD Red HDDs, it delivers read/write speeds of up to 1,016 MB/s. Even with a single 1 TB WD Red SSD, users can enjoy read speeds of 510 MB/s. This exceptional performance ensures rapid data access and transfer, perfect for professionals and enthusiasts alike.
Expandable NAS Integration
Optimized for TerraMaster NAS devices running TOS 5.1 or higher, the D4-320U connects via USB to expand storage pools and create arrays through the robust TOS system. This feature makes it a powerful companion for users looking to scale their NAS capacity with ease.
Plug-and-Play Simplicity
The D4-320U offers true driver-free, plug-and-play functionality, seamlessly supporting macOS, Windows, Linux, Ubuntu, TrueNAS, Unraid, and more. Compatible with USB protocols, it connects effortlessly to PCs, TVs, servers, and set-top boxes. Included 0.8 m USB A-to-C and C-to-C cables ensure compatibility with USB 3.0, 3.1, 3.2, Thunderbolt 3, and Thunderbolt 4 interfaces for stable, high-speed connectivity.
Robust Safety and Efficiency Features
Automated Backups Made Easy
With TerraMaster's TPC Backupper for Windows (8/8.1/10/11), users can schedule incremental or differential backups of folders and partitions to the D4-320U or a TerraMaster NAS.
More TerraMaster Storage Devices
The D5-310 5bay RAID storage device was released at the same time, forming a "enterprise + personal" dual product line layout with the D4-320U. Users can now purchase new products through TerraMaster Official Mall and authorized channels, and enjoy a 2-year warranty service.

Robust Safety and Efficiency Features
- Power Protection: Advanced safeguards prevent damage from mismatched power inputs, ensuring hardware longevity.
- Power Recovery: Smart memory resumes the device's prior state after power outages—staying off after a normal shutdown or auto-starting post-disruption—ideal for unattended server or NAS setups.
- Intelligent Hibernation: Drives enter sleep mode with the host system, reducing wear and energy use while extending lifespan.
- Quiet Cooling: A smart, temperature-controlled low-noise fan and optimized airflow keep drives cool and quiet, even under full load.
