Everyone needs to be backing up their computers with an external HDD of some sort
When it comes to keeping all the data on your computer safe and secure, you need to be backing your data up. Having you data on your computer in folders neatly is going to do nothing for you if your hard drive goes bad. Take it from me, when a hard drive does go bad often the first hint you get is the blue screen of death.

Not backing up your files, photos and other content can easily result in the loss of all your important things. For instance if you take all your photos on a digital camera and archive them on your computer, one crash can mean all of those irreplaceable family photos are just gone. If you have lots of important business documents and files, you can lose them all as well.
Typically, when you buy an external HDD it will be a USB drive that plugs into a port on your computer. You may be able to use USB 3.0 if your computer is newer. There may also be other ports available for external storage like eSATA as well. If the external HDD is designed for backing up data, it will typically come with software for backups. The first time the software will generally back up everything from photos and documents to your email. After that, it will only back up files that have changed so the backup doesn't take as long.
When you are shopping for an external HDD, you will want to buy one that has the most storage capacity you can afford. You don't want to buy an external storage device and then have it run out of storage space in a few months. Be sure that the drive you buy supports your computer be it Mac or Windows or be prepared to reformat the drive to support your machine. You will also want to be sure that the HDD comes with the cables you need to use it. Read on for some of my picks of the best external HDDs around.
