TerraMaster D9-320 9-Bay DAS Drive Enclosure

The TerraMaster D9-320 is a professional 9-bay DAS enclosure built for large-scale storage expansion and demanding data workflows. It supports up to nine 3.5" or 2.5" SATA HDDs and SSDs with a maximum combined capacity of 216 TB, providing ample space for 4K and 8K video projects, multimedia libraries, backups and enterprise archives. Each drive operates independently by default, while software RAID can be configured through the host operating system.

A USB 3.2 Gen 2 interface delivers bandwidth of up to 10 Gb/s, with read speeds of up to 1016 MB/s and write speeds of up to 960 MB/s when multiple SSDs are used. The enclosure also includes both USB-C to USB-C and USB-A to USB-C cables for broad compatibility with modern workstations. An additional 10 Gb/s USB Host port enables daisy-chain expansion, allowing multiple compatible storage devices to be connected through a single computer connection.

Independent power switches for each drive allow unused bays to be powered down individually, reducing energy consumption and protecting stored data through safe drive disconnection. Automatic disk sleep and Power-On Recovery further improve reliability in continuous operation. Three temperature-controlled fans and four integrated sensors maintain optimal cooling while keeping operating noise to approximately 22.5 dB(A). The D9-320 is fully compatible with Windows, macOS, Linux, Unraid, TrueNAS and Proxmox, making it well suited for professional studios, servers and advanced desktop storage systems.
