Its space-saving form is ideal for data centers, closets, or offices, offering a centralized storage solution for SMB and SOHO users.
High Speed: Utilizing the USB 3.2 Gen2 protocol, the D4-320U delivers data transfers up to 10Gbps. In real-world tests, it achieves read/write speeds up to 1,016MB/s with four HDDs, and 510MB/s with a single SSD.
Super-large Storage Space: Supports up to four 3.5″ or 2.5″ SATA HDD/SSDs, with a maximum per-drive capacity of 30TB for a total of 120TB. Note: The enclosure operates in standalone disk mode and does not support RAID arrays.
Expandable NAS Integration: When connected via USB to a compatible TerraMaster NAS running TOS 5.1 or later, the D4-320U can be used to create additional storage pools and expand your NAS capacity directly through the TOS interface.
Plug and Play, Highly Compatible: A driver-free device that works instantly with Windows, macOS, and Linux. It includes both USB-C to C and USB-C to A cables (0.8m each), and supports connections to USB 4.0, 3.2, 3.1, 3.0, and Thunderbolt 5/4/3 interfaces.
