WD has released its My Passport Ultra line of portable hard drives, which combine additional layers of data protection with USB 3.0 connectivity in a slim, compact design and four color choices.

Available in 500 GB, 1TB and new 2TB capacities, My Passport Ultra portable hard drives have built-in WD SmartWare Pro backup software with Dropbox integration, hardware encryption and password protection. A protective pouch is included with the My Passport Ultra to help shield it.

My Passport Ultra portable hard drives are protected by a three-year limited warranty and are available from the WD store at wdstore.com and at select retailers and distributors. The My Passport Ultra 500GB has a manufacturers suggested retail price of $99.99 USD, and the My Passport Ultra 1TB is $129.99. (The 2TB version is due later this year.)
