Four-bay 3.5-inch SATA enclosure

The Mediasonic HF7-SU31C holds four 3.5-inch SATA hard drives or SSDs, each up to 30 TB. It connects through a USB 3.2 Gen 2 Type-C port with a 10 Gbps link. The metal and plastic chassis includes a revised front door with an air intake and a temperature-controlled fan.

Verify host port and drive brackets

Your computer must provide a USB-C port that can run at 10 Gbps to reach the enclosure’s peak throughput. The tray mechanism is built for 3.5-inch drives; 2.5-inch SATA drives need a separate bracket adapter that is not included. No RAID controller is present inside the unit.

Included cable, power and tools

A 3.3 ft USB-C to USB-C cable with an E-Mark IC, an AC adapter with power cord, four drive handles, eight mounting screws and a screwdriver ship in the box. The bundle lets you install drives and connect to Windows 10 or 11, macOS 10.8 or later, or Linux without extra purchases. Software RAID can be configured on the host if desired.

The package includes the HF7-SU31C enclosure, a 3.3ft USB-C cable with E-Mark IC, power adapter and cord, four drive handles, eight screws and a screwdriver. A bracket adapter is required for 2.5-inch SATA drives and is sold separately.

It accepts four 3.5-inch SATA I, II or III hard drives up to 30TB each. It also supports 2.5-inch SATA drives up to 30TB each when the separate bracket adapter is used.

What does the 10Gbps USB 3.2 Gen 2 rating mean for actual transfer speeds?

The USB 3.2 Gen 2 Type-C interface provides up to 10Gbps bandwidth, while each SATA drive runs at up to 6.0Gbps. Real-world throughput depends on the drives installed and the host system.
