Six-bay USB 3.2 Gen2 enclosure

The TerraMaster D6-320 is a six-bay direct-attached storage enclosure that connects through a USB 3.2 Gen2 Type-C link running at 10Gbps. It accepts up to six 3.5-inch or 2.5-inch SATA hard drives and 2.5-inch SATA SSDs, each up to 22TB, for a total raw capacity of 132TB. The unit operates in single-disk mode only and requires no driver installation on Windows, macOS or Linux. An intelligent temperature-controlled fan adjusts speed automatically to keep drives cool.

Suited for JBOD archives not RAID arrays

This enclosure suits users who want a simple, driver-free way to attach multiple large SATA drives as independent volumes for backups, media libraries or archival storage. It is not for administrators who need hardware RAID 0, 1, 5 or 10 presented as a single logical volume, nor for anyone needing drive types beyond SATA. The lack of built-in array management means each drive appears separately to the operating system.

USB 3.2 Gen2 10Gbps interface decides throughput

The single specification that determines whether this enclosure fits a workflow is the USB 3.2 Gen2 10Gbps host connection. With six drives installed the manufacturer cites sequential throughput up to 1,030MB/s, while a single drive can deliver up to 510MB/s. If the host system only provides a 5Gbps or slower USB port, those speeds cannot be reached.

Questions about this item

What real-world throughput does the USB 3.2 Gen2 10Gbps interface deliver with six drives?

With six SATA HDDs installed, simultaneous read/write reaches 1,016MB/s; a single SATA SSD hits 510MB/s read.

Which drive sizes and maximum capacity per bay does the D6-320 accept?

It takes 3.5-inch and 2.5-inch SATA HDDs or 2.5-inch SATA SSDs, each up to 22TB for a total of 132TB.

How do I install drives and what common mistake should I avoid?

Slide each SATA drive into a hot-swap tray, secure it with the supplied screws, insert the tray until it clicks, then power on — forgetting the tray screws causes disconnects and recognition failures.
