Product Overview

Today's storage-hungry technologies are making it tough for your computer system to find room for everything you want to store. Digital cameras, DV camcorders, MP3 players and other recording devices-not to mention Internet downloads- are packing your system full. You need more storage capacity. You'd like to add it the easy way. Western Digital has the way.
 
With two ways to back up your data, automatically or on-demand, WD Dual-option Combo drives are the ideal solution for saving your valuable pictures, music, video, and data files.
