[citation][nom]mikepaul[/nom]Boy, I wish Microsoft would allow even some network backup software to be used on the 360, let alone external storage. Right now, your game save die when your HD dies. Sony seems rather cavalier in the area of possible piracy, while Microsoft does what it can so nobody does anything evil, not even altering game saves to get free Achievements. I find their valor quite annoying...[/citation]A memory card would be plenty for saved games. Anything else (videos, DLC, full downloaded games) you can re-download as many times as you need to, from XBL. Although to be fair, the HDDs they use have a pretty good track record.
