D9-320 9-Bay Hard Drive Enclosure

9-Bay Hard Drive Enclosure

Designed specifically for media storage and data expansion: The TerraMaster D9-320 is engineered for large-capacity multimedia storage (such as 4K/8K video footage, audio-visual collections) and server storage expansion. Supporting high-speed multi-drive read/write operations, it meets the massive storage demands of professional studios, enterprise-level servers, and personal media enthusiasts.

The D9-320 offers powerful storage expansion capabilities, supporting up to 9 hard drives. With a maximum single drive capacity of 22TB (compatibility with larger hard drives pending verification), it delivers up to 198TB of storage space, fully meeting the demands of various large-scale data storage. Note: This device operates in single-disk mode by default. RAID configurations require third-party software RAID management tools.

Leveraging USB 3.2 Gen2 protocol, it achieves transfer speeds up to 10Gbps. When equipped with 9 hard drives, it achieves actual read/write speeds up to 1016MB/s (simultaneous read/write with 9× 8TB WD Red HDDs). With a single drive, read speeds up to 510MB/s (WD Red 1TB SSD). The D9-320 delivers outstanding performance for both multi-drive and single-drive operations.

The rear of the D9-320 is thoughtfully equipped with a high-speed 10Gbps USB Host expansion port, allowing multiple storage devices to be daisy-chained for further capacity expansion. When USB ports on the computer are limited, the D9-320’s built-in USB Host port provides an effective solution to this challenge.

Fully compatible with 8 major operating systems, this product strictly follows USB protocol standards, seamlessly integrating with computers, TVs, servers, set-top boxes, and more, offering users unprecedented convenience and flexibility.

Supported systems: Windows 10/11, Windows Server 2015/2019, Mac OS, major Linux distributions, Kylin V10 SP1, UOS, Unraid, TrueNAS, Proxmox.

Interface Compatibility:Equipped with a USB Type-C interface and comes with two cables: a 0.8-meter USB-A to USB-C cable and a USB-C to USB-C cable. Seamlessly connects to USB 3.0/USB 3.1/USB 3.2, Thunderbolt 3/Thunderbolt 4 interfaces for stable, high-speed transfers.

Drive Compatibility:Supports various types of hard drives, including 3.5-inch SATA hard drives, 2.5-inch SATA hard drives, and 2.5-inch SATA SSD.For optimal stability and performance, consult TerraMaster's hard drive compatibility list before purchasing.

Independent Power Supply for Drives: The product is equipped with 9 independent drive power switches and a master power switch, allowing users to individually power down unused drives,.This feature effectively saves energy and significantly extends the lifespan of the hard drives.

Intelligent Power-Off Protection: During the process of turning off the hard drive power, the system automatically ejects drives safely from the PC, ensuring drive heads park properly before cutting power. This design eliminates risks of head damage from sudden power loss during high-speed operation, protecting both drives and stored data. Unlike traditional methods that may cause abnormal SMART (Power-Off Retract Count) values, the D9-320’s power management system fully avoids this issue.

The device is equipped with a power-onrecovery memory function.After normal shutdown, the device remains off upon power restoration. After abnormal power loss, it automatically restarts when power resumes, enabling automatedunattended management with servers.NAS, and other devices.

The D9-320 supports an intelligent sleep function, automatically entering sleep mode when the computer system goes into standby (e.g., USB device safe removal, computer sleep, or shutdown). This reduces drive operating time, minimizes motor wear, and extends drive lifespan, ensuring reliable protection for your storage assets.

Equipped with a second-generation intelligent temperature-controlled fan system, the D9-320 delivers efficient cooling while maintaining ultra-quiet operation, helping extend the lifespan of both the device and hard drives. Four internal temperature sensors enable precise thermal monitoring and adaptive fan speed adjustment, maintaining optimal drive temperatures. Optimized airflow design reduces component resonance and noise, even under full load, ensuring a silent workspace.

Constructed with a robust unibody metal design, it guarantees long-term stability and reliability, perfectly suited for high-intensity operational environments.

With the user-friendly TPC Backupper Windows PC backup tool, you can enable scheduled backups. Simply connect the device to your computer, install the client, and set up tasks to back up folders and disk partitions from your Windows PC to TerraMaster USB devices or NAS storage servers. It supports incremental and differential backup strategies, compatible with Windows 8/8.1/10/11 systems, providing reliable protection for your important data. Download now.
