Keeping your data double-safe
In just a few simple steps, you can set up automatic and continuous back up for all the computers on your network. But wait, there’s more… there are two drives in this system and we’ve set them up to mirror each other using RAID technology. The system automatically and continuously maintains a second copy of your data for double safe data protection. If one drive in this two-drive system ever fails, the system continues to run and your data is safe. How's that for peace of mind?

Keeping the files on your laptop backed up without even thinking about it
You’ve been out at Joe’s Coffee Shop writing your novel and now you’re home and you know you should back up your work. Sigh. With the My Book World Edition II drive it’s no longer a chore, in fact, it’s easy. Just turn on your laptop and log into the home network. That’s it. Your files will be backed up automatically over your wireless network. It’s easy to set up in just a few clicks, and once you’re done it’s always automatic and you can stop thinking about it.

Playing music and video files on your TV
Your epic trip-to-Africa home video is here on the computer in the den. Your big, beautiful new plasma TV is there in the family room. How do you get that video from here to there? My Book World Edition II can be your home's central media hub. From it you can stream photos, music, and videos to your home entertainment center or any connected PC, Mac, or DLNA certified game console or media player. All you need is the My Book World Edition dual-drive system and a digital media adapter or a game console like X-Box 360 or Playstation 3, and your epic adventure is there on the big screen.

Playing all your iTunes music on any computer in the house
You use iTunes to manage your music and so does the rest of the family, so there are music files on all of your family’s computers. With the My Book World Edition dual-drive storage system, you can put that music all in one place so that everyone can listen to it. Store all your family’s iTunes music on the drive. Find the drive on any computer on the network. Open iTunes, and, ta-da, there’s all your music.

Getting to your data no matter where you are
You’re out of town, interviewing for a new job. You need a new copy of your resume and it’s only on your home computer…which is turned off. Yikes! But you’re OK, because you stored the resume on your My Book World Edition drive. The drive is always on, and you can get to it through the Internet, any time, anywhere. Excellent! Now you can knock ‘em dead in the interview.
