Every time you use a computer, you are relying upon a hard drive. A hard drive contains the data it needs to operate the computer plus space for you to save your files. Hard drives are thus integral parts of computers.
Because hard drives have the potential to crash, or possibly become infected by viruses, it is wise to have an external hard drive. An external hard drive is like the hard drive inside your computer, but it can be plugged in and then removed again. You can backup all of your important files onto the external hard drive, which allows for you to have a secure copies of your most important data in case something happens to your computer. External hard drives also allow for you to transfer big files – files that can’t simply be sent as email attachments – from one computer to another.
Why take a chance with your data? External hard drives can get a little expensive, but you don’t have to buy one for hundreds or even thousands of dollars. There are many good options with large storage capacities, or space to store a lot of data that you can purchase for under $100. Websites such as Newegg.com can help you compare prices between external hard drives to get the best deal.
