You see many stores and web pages these days selling external hard drives, but you really need one??, a couple years ago nobody had one.

Times have change,and so the customs of modern society. Many used the external hard drive  to put all the pictures and family videos, this could be a good way to store this information, it has the advantage that you can move it to any computer you want and if your computer crashes or stops working, you have back up all the information in the external hard drive, it really hurts to lose all your family and friends pictures and never see it again, a good way to avoid that happening is to back it up in DVD’s and an external hard drive.

Another function it could have is in your job, when you have to office, and you have clients coming some days to one office and others days to the other, you easily transport all your documents, just from carrying a small portable 160 gb external hard drive, a good example of this situation is a doctor who treats his patients in different location, and if a patient comes he has all the medical history of that person.

If your computer is a la laptop, you can`t put an internal hard drive as easily as a desktop, so if you want all your information of years in your laptop, this could be an issue, it would be a good idea to buy an external hard drive and just plugged in and you could have even 4Tb of memory in your laptop, that pretty much is a world of information and it cost some money, you would probably need just a 500gb external hard drive or smaller.

So as you may see an external hard drive is really help full these days, it has many applications.
