The all-metal enclosure features an unusual design with nine physical power switches and a main control switch. Thus, unused drives can be turned off independently of the others, reducing power consumption by up to 70%. The intelligent UPS power-off protection system automatically parks the heads and protects the data cache in the event of sudden failures.
D9-320 supports nine drives in single mode with a maximum capacity of 22 TB per drive. Thus, the total capacity can reach 198 TB. As noted by TerraMaster, real-world tests show read/write speeds of 1016 MB/s when nine 8 TB WD Red hard drives are working in parallel and 510 MB/s for a single 1 TB WD Red SSD.
The device is equipped with a USB 3.2 Gen2 interface. D9-320 is compatible with USB 3.0/3.1/3.2, USB 4, Thunderbolt 3, and Thunderbolt 4 ports. Mixed installation of 3.5\" and 2.5\" HDDs and SSDs is supported. An additional USB Host expansion port with a bandwidth of 10 Gbps is provided, allowing multiple storage devices to be connected in a chain.
Users can expand storage for NAS and PCs, including Windows, macOS, Linux, TerraMaster OS, Unraid, TrueNAS, and Proxmox systems.
The D9-320 9-bay hard drive enclosure is offered by TerraMaster for 52,000 rubles with a 2-year warranty and lifetime technical support.
