Professional storage brand TerraMaster proudly unveils its revolutionary product, the D9-320, a 9-bay intelligent storage enclosure. As a flagship model featuring an innovative "independent drive power control system," the D9-320 offers a massive 198TB storage capacity, 10Gbps high-speed transmission,
and precise nine-channel power management, providing professional-grade storage expansion solutions for small and medium-sized businesses, NAS users, and tech enthusiasts.

Three Major Breakthroughs Set a New Industry Benchmark

9-Channel Independent Power Management
The D9-320 introduces an innovative design with nine physical power switches plus a master control switch for dual protection. Users can precisely shut down idle drives, reducing power consumption by up to 70%. Paired with a UPS intelligent power-off protection system, it automatically performs head parking and data cache protection during unexpected power outages, improving data safety by 300% compared to traditional enclosures.

10 Gbps High-Speed Data Transmission
Equipped with a USB 3.2 Gen2 interface, the D9-320 achieves transfer speeds of up to 10 Gbps. Real-world tests show read/write speeds of 1016MB/s with nine parallel 8TB WD Red HDDs and 510MB/s for a single 1TB WD Red SSD, ensuring high-speed performance for both multi-drive and single-drive setups.

Massive Storage Capacity and Expansion
The D9-320 supports nine drives in single-disk mode, with a maximum single-drive capacity of 22TB, delivering up to 198TB of total storage. It seamlessly expands storage for NAS and PCs, including Windows, Mac OS, Linux, TerraMaster OS, Unraid, TrueNAS, and Proxmox systems.

Innovative Power Management and Data Protection
The D9-320 introduces a revolutionary power management system with nine independent drive power switches and a master power switch. Users can turn off idle drives to save energy and extend drive lifespan. Its intelligent power-off protection ensures safe drive ejection and head parking before shutdown, preventing damage from sudden power loss—a common issue affecting SMART metrics in traditional enclosures. Additionally, the power recovery function either shuts down the device after a normal power-off or auto-restarts after an unexpected outage, making it ideal for unattended server and NAS setups.

Energy-Saving Smart Features
The D9-320 includes an intelligent sleep mode that syncs with a PC’s sleep or shutdown state, reducing drive wear and energy consumption. It features a second-generation smart cooling system with four precise temperature sensors and adjustable fan speeds, maintaining optimal operating temperatures even under full load while minimizing noise. This ensures longevity and a quiet working environment.

Broad Cross-Platform and Device Compatibility
Designed for versatility, the D9-320 integrates seamlessly with multiple operating systems, including Windows, Mac OS, Linux, TerraMaster OS, Unraid, TrueNAS, and Proxmox. Its USB Type-C interface is compatible with USB 3.0/3.1/3.2, USB4, Thunderbolt 3, and Thunderbolt 4 ports. It supports mixed installation of 3.5" and 2.5" HDDs/SSDs.

NAS Storage Expansion
The D9-320 is deeply compatible with the TOS system, offering one-click expansion of TerraMaster NAS storage pools. It supports creating JBOD/RAID, TRAID, and TRAID+ array modes, effortlessly expanding NAS storage capacity.

Daisy-Chain Expansion
The device includes an additional 10 Gbps USB Host expansion port, enabling multiple storage devices to be daisy-chained for further capacity expansion. When facing a shortage of USB ports on a computer, the D9-320’s USB Host interface provides a perfect solution.

Durable All-Metal Build
The D9-320 features a robust all-metal chassis capable of withstanding high-intensity workloads. For PC users, it also offers the free TPC Backupper tool on Windows, providing scheduled backups with incremental and differential options to ensure data security.

The TerraMaster D9-320 is now available for purchase through the TerraMaster official store and authorized channels, with a 2-year warranty and lifetime technical support.
