Choose a size. Find the size of the files you want to back up, and estimate how much they'll grow in the future. To find the size of a drive, double-click on "My Computer," and right-click on the drive you want to know the size of. Select "Properties," and look under "Used Space." To find the size of a file or folder, right-click it, and select "Properties." Look under "Size." Ask yourself how many backups you'll be storing on the drive, how long you want to keep the drive, and what size backups you'll be making at that point--to choose the right size.
Decide between mechanical and a solid state disk. Mechanical is really the only option here. SSDs aren't nearly large enough or cost-efficient to use for backup purposes.
Decide on an internal or external Hard Drive. Internal drives are slightly cheaper, and installed inside your computer. If you get this kind of drive, you'll need to know whether you need an IDE or SATA drive. For info on finding out, see the resources below. External drives are best if you'll be backing up data from multiple computers, or if you want to store your backup data in a location away from your computer. For help in choosing an external hard drive, check the resources.
Consider what speed you want. Backup hard drives don't need to be fast, so the standard 7200RPM drive will work perfectly.
Choose your style. If you're getting an internal drive, style isn't an issue, but if you're going with an external drive, it could be. You'll probably be looking at the drive every day, so choose one that you don't just like, but love.
