Why everyone should have a external hard drive.

An external hard drive should be a necessity for everyone who has a computer with valuable information and files stored on it. A external hard drive can provide security and peace of mind to users who hold irreplaceable files on their computers, but don't want to back up gigabytes of files to individual DVDs. There is chance your external hard drive could fail so DVDs will always be needed for the most irreplaceable files. Below are a few of the reasons why I think everyone should have an external hard drive.

1. Back up Operating System
One of the best reasons to have a external hard drive would be the luxury of having a back up operating system just in case something happens to your primary hard drive and default operating system. GNU/Linux can be easily installed to a external hard drive the same way it is installed to a internal hard drive. A external hard drive is also a way to try Linux without it touching your primary hard drive.




2. Security
A external hard drive can provide a since of security for those who are worried about others viewing there private files and documents. Some external hard drives are small and compact so they can be carried around with ease. These small and compact drives allow security concerned people to take there sensitive information where ever they go. You can either create diskless computers and run the operating system from the external hard drive to stop others from using or accessing your computer.

3. Back up large amounts of data
This may be the most obvious reason to get a external hard drive, but not the most important. Getting a external hard drive just to back up a small to medium amount of data is a waste of money. You can simply back up data and files to a DVD. You should only get a external hard drive if there's a need to back up large amounts of data and important files. Some may wish to clone there primary hard drive or have large media collections they want to have copies of.
