  • Independent power per bay extends drive life and saves energy

  • USB 3.2 Gen2 10Gbps delivers up to 1030MB/s with nine HDDs

Nine-bay DAS with independent power

The TerraMaster D9-320 is a nine-bay direct-attached storage enclosure that accepts 3.5-inch or 2.5-inch SATA hard drives and SSDs. Each bay has its own power switch alongside a master control, letting users spin down unused drives to save energy and extend hardware life. It targets media professionals, server operators and enthusiasts who need massive capacity without RAID complexity.

Sustained multi-drive throughput

With nine drives installed the enclosure delivers real-world read and write speeds up to 1016 megabytes per second over its USB 3.2 Gen 2 link. A single SSD reaches up to 510 megabytes per second. The independent power design means drives only draw current when active, so thermal load stays proportional to the number of spinning disks during long ingest or backup sessions.

USB 3.2 Gen 2 bandwidth ceiling

The Type-C connection caps at 10 gigabits per second and is backward compatible with USB 3.1, 3.0 and Thunderbolt 3, 4 and 5 hosts. Total raw capacity tops out at 270 terabytes using 30-terabyte drives, though the supplier notes 26-terabyte drives are verified for 234 terabytes. No hardware RAID is present; multi-drive arrays require software management on the host.

Questions about this item

How loud or hot does the D9-320 get when all nine drives run continuously?

Nine independent power switches let you spin down unused drives, reducing heat and noise while an intelligent shutdown parks heads safely.

Which cables or host ports do I need to connect the D9-320?

The box includes Type-C to C and Type-A to C cables; the host must provide a USB 3.2 Gen2 10Gbps Type-C or Thunderbolt 3/4/5 port.

Will my existing 3.5-inch SATA drives work in the D9-320 without RAID?

Yes, each bay accepts 3.5-inch or 2.5-inch SATA HDDs or SSDs up to 30TB and the enclosure runs in single-disk mode by default.
