High-speed file transfer. Massive capacity.

My Book Duo is the ultimate dual-drive storage solution offering the capacity and security you need, with blazing-fast transfer speeds, encrypted hardware RAID and comprehensive local backup options.

Quickly save and organize your files
Free up valuable space on all your computers. Save and organize your entire media collection on your My Book Duo with ultra-fast data transfer speeds.

Massive capacity
My Book Duo is your storage vault. With up to 12TB of capacity, you can save and protect all your photos, videos, music and important documents in one safe place.

Speed and security with hardware encrypted RAID
True hardware RAID provides an independent processor to manage RAID volumes, maximize bandwidth and sustain performance and reliability.

Multiple data management options
Use the default performance mode (RAID 0) for faster data transfers and maximum capacity. With safe mode (RAID 1) half the capacity is used to store your data and the other half is used for a duplicate copy offering twice the data protection. You can also format this in JBOD to use the drives individually. And with the 256-bit AES hardware encryption feature, you have the peace of mind that your files are secure.

Complete backup solutions to secure your data from loss
My Book Duo offers a comprehensive backup solution to help protect your media collection and important files. 

Ultimate security with password protection
Gain peace of mind knowing that your data is protected from unauthorized access with password protection for your privacy.

Flexible connectivity with two USB expansion ports
Expand your storage capacity and de-clutter your workspace with two additional USB 3.0 ports on the back of your My Book Duo. Connect additional drives to expand as your storage needs increase, and at the same time you can charge your smartphones or tablets to create the ultimate, organized workspace.

Easy to set up, easy to use
Ready to use right out of the box with pre-formatted NTFS for Windows OS users. The drive can also be easily reformatted for Mac® OS X.

Ultra-reliable with WD Red drives
My Book Duo ships with WD Red drives inside. These drives are designed and tested for reliability and optimal performance in small RAID environments. 

User serviceable enclosure
Ready to upgrade your drives to expand storage capacity? With the simple push of a button, pop open the enclosure and insert new drives with ease. No tools required.
