The My Book Duo 4TB (2 x 2TB) Two-Bay USB 3.0 RAID Array from WD comes with two WD Red hard drives that are pre-configured in RAID 0 to deliver data transfer rates of up to 290 MB/s. Its two drives support 4TB of storage in a 2 x 2TB configuration and are formatted as NTFS for Windows 8 or higher, as well as Windows 7 and Vista. The drives can also be reformatted for use with Mac OS X, configured in RAID 1 for data redundancy, or in JBOD to use each drive individually. WD has outfitted this array with two USB 3.0 ports which have data transfer speeds up to 5 Gb/s, while also being backwards compatible with USB 2.0 at speeds up to 480 Mb/s. For those who are concerned about drive security, this RAID array is equipped with AES 256-bit encryption.

The My Book Duo is well suited for tasks such as high-capacity external storage and backup. It operates using 100-240 VAC at 47-63 Hz and includes WD SmartWare, WD Drive Utilities, and WD Security software, as well as a USB cable, and an AC adapter. It is protected by a limited 2-year warranty.
Save and Organize Your Files
Free up valuable space on all your computers. Save and organize your media collection on your My Book Duo with fast data transfer speeds up to 290 MB/s
Speed & Security with Hardware Encrypted RAID
A true hardware RAID provides an independent CPU to help 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
Backup Solutions to Help Secure Your Data from Loss
The My Book Duo offers a comprehensive backup solution to help protect your media collection and important files:
  • Integrated Backup Software - WD SmartWare Pro works quietly in the background to help protect your data using minimal PC resources. Select continuous backup mode to automatically back up your files as they change, or select the scheduled backup option to automatically back up your files at specified intervals
  • Cloud Backup with Dropbox - Save a second copy of your files to your Dropbox cloud account using WD SmartWare Pro. Then, view, open, and share the files you have backed up using Dropbox. And for more ways to protect your important content, you can also back up your Dropbox account to your My Book Duo
  • System Level Backup - Acronis True Image WD Edition software backs up your computer's hard drive at the system-level for total data protection. With a system-level backup to My Book Duo, you can restore your computer's hard drive in the event of a system crash or restore select system files after they have been corrupted or accidentally deleted
Security with Password Protection
Password protection helps to guard your data from unauthorized access
