Eight-Bay 3.5-Inch Enclosure for Desktop Storage

The Mediasonic PROBOX holds up to eight 3.5-inch SATA hard drives, each up to 18 TB, or eight 2.5-inch SATA drives or SSDs up to 12 TB with a separate bracket adapter. It connects to a desktop PC through USB 3.0 or eSATA and uses a single front-panel button to choose which interface is active. A temperature-controlled fan pulls air from the front and exhausts it at the rear.

Suits Builders Needing High-Capacity External Arrays

This unit fits users who want a large, direct-attached storage pool for backups, media libraries or archiving and who can work with Windows 10 or 11, or Mac OS 10.3 and later. It will not serve buyers who need Linux support, who require 4Kn native drives, or who use drives with the power-disable feature such as certain enterprise models. A host eSATA port must support port multiplication for all drives to appear.

One Active Interface at a Time

Only one connection, USB 3.0 or eSATA, can be used at any moment; the button toggles between them. USB 3.0 delivers up to 5.0 Gbps and eSATA up to 6.0 Gbps, matching the SATA 3 6.0 Gbps drive link.

Questions about this item

Does this enclosure need a USB 3.0 or eSATA port on my computer to work?

Yes, it connects through a single USB 3.0 or eSATA port; you select the active interface with the front button and can use only one at a time.

Will my existing 3.5-inch SATA drives up to 18 TB each be recognised in this unit?

The enclosure supports any brand of 3.5-inch SATA drive up to 18 TB per bay, but 4Kn native drives and Power Disable Feature drives such as WD Enterprise or HGST models are not supported.

How can I confirm the drives are visible after I connect the enclosure?

With the computer on, the enclosure powers on automatically; check your OS disk utility — Windows 10/11 or Mac OS 10.3 and later — to see all mounted volumes.
