The newest addition to Western Digital’s line of Network Attached Storage (NAS) devices is the My Book Live Duo. As the name would suggest it contains 2 storage drives that are capable of acting in spanning or data protection modes. In spanning mode the two drives combine to form one large volume, whereas in data protection mode one drive is used to store your data and the other is used to store a duplicate copy. The device also does the other things that are now expected out of modern NASes, it will stream your media or iTunes Library to any DNLA certified device such as blu-ray players or game consoles, it performs automated backups using the included WD SmartWare software or it works with Time Machine, and it provides internet and mobile access using its iOS and Android apps.
