High-capacity desktop RAID storage

The Western Digital My Book Duo provides 44TB of storage in a desktop form factor. It ships configured in RAID-0 for maximum capacity and throughput. The unit is formatted NTFS for immediate use with Windows systems. Hardware-based 256-bit AES encryption protects data with password control.

Connectivity and daily workflow

A USB 3.2 Gen 1 Type-C port links the drive to the host, with a USB-C to USB-C cable and a USB-C to USB-A cable both included for broad compatibility. Two front-facing USB 3.2 Gen 1 hub ports allow additional peripherals to be connected through the enclosure. An AC adapter supplies power, and a disk replacement tool is provided for drive maintenance.

Thermals and power in normal use

The enclosure uses a desktop chassis measuring 7.09" x 3.94" x 6.30" and weighs 5.80 lbs to house the dual-drive array. Passive and active cooling manage heat during sustained transfers over the 5Gbps interface. The external power brick keeps the unit running without drawing bus power from the host.

Questions about this item

What real-world speed does the USB 3.2 Gen 1 Type-C interface cap at?

The USB 3.2 Gen 1 connection runs at 5Gbps, so sustained transfers top out around that bandwidth in practice.

What clearance does the 7.09 x 3.94 x 6.30 inch chassis need on a desk?

Allow at least those dimensions plus a few centimetres behind for the AC adapter and the two hub cables.

How do you set up the hardware encryption, and which step is often missed?

Install the included management software, set a password to activate the 256-bit AES encryption, then register the recovery key — skipping the key backup is the common mistake.
