WD My Book Duo Overview
The WD My Book Duo has a pretty simple design to it. It basically has a large rectangular shape, much like many dual-bay NAS devices out there. The top sort of has this glossy plastic, whereas the bottom has more of a design to it. This design allows the My Book Duo to easily fit on your desk and look good, but not look out of place either. For those wondering the official dimensions are 160 mm x 100 mm x 180 mm (LxWxH).
The front of the drive is pretty plain, all you have is a WD logo towards the top. Moving over to the sides they are all plain as well. I really like that there is not some big WD or My Book logo on the side actually.
Flipping around to the back you’ll find all of your connections. These include a USB 3.1 Type-C port, two USB 3.0 ports, power connection, and Kessington lock port. The two USB 3.0 ports are actually ports to connect other devices. This is nice as it sort of serves as a hub for your other USB devices. There is also a fan on the back of the drive to keep your drives nice and cool.
The drives in the WD My Book are extremely easy to remove. WD includes a “disk replacement tool” which basically allows you to remove to the top part of the drive. Once you have the top removed you can easily remove the drives as they are installed in removable trays. WD is using their WD Red “WD100EFAX” drives which are made for NAS devices. All WD My Duo’s ship with WD Red drives pre-installed.
