Most are simple to use and setup is simply a matter of plugging a cable into your desktop PC. An external drive may also provide you with far more available disk space if you just happen to fill up your internal hard disk.

So how do I choose which one is ideal for me?
As you might expect, there are many brands and models to choose from. A number of the more well known brands are Western Digital, LaCie, Maxtor, Seagate, and Iomega. They all offer choices that vary primarily by storage capacity and rate. Let us start with storage capability.
How large a drive should you get?
External drive capability is typically listed in Gigabytes (a Gigabyte is a thousand bytes or a million megabytes, which will be approximately 11/2 CDROM disks ). When selecting the best external hard drive, you need to decide what you will be using the drive , and about how much information you will be putting on the driveway. An easy way to get a ballpark amount of how large your existing data folder is would be to, as an instance, create a folder to your photos. You’d then cut and paste all your pictures to this folder. Now, to determine how big this folder is, just click the folder with your mouse and choose Properties from the resulting menu. The General tab of the Properties window will then inform you how large the folder will be. Do this again for your audio and other files then add up all of the folder sizes to get the entire size. Once you’ve got a last total, multiply that number by 3. That will provide you an estimate of the minimum size your external drive should be.
For example, state your folders include up to approximately 50 Gigabytes (50GB) of data. Multiplying 50 X 3 would equivalent 150GB. This would be your minimum size external drive. You always need to let room for future storage needs. If you are able to spend a larger drive, get it.
