Bjorn3D has posted a review of the Seagate 400GB Pushbutton Backup USB 2.0/FireWire HDD

All of us have movies, pictures and/or music that we treasure and would hate to lose. You may have already heard or read it a thousand times, but you really should back up any data that is important to you. Before you reach for those 3.5" floppies, you should realize that your backed up data is only as good as the media you put it on, which is why you should steer clear of floppies, especially when there are so many superior options available today. Besides, you can't fit much more than a few school papers on a floppy.

One common option employed is to install and utilize a spare hard drive. In the end this is probably the most convenient option because your backup media (the spare HDD) is right at your finger tips every time you use that PC. Unfortunately, if it's installed in your PC, that solution isn't very easy to take with you when you're on the go. This is one of the reasons external solutions are so popular; they make back up and sharing easy and convenient. Flash memory and hard drives are the most common external storage types for personal use. While I can't live without my 2GB USB flash drive, it just isn't big enough to back up all my media files. But, Seagate's 400GB Pushbutton Backup USB 2.0/FireWire external hard drive easily solves that problem.
