An external hard drive is a very comfortable solution for all those seeking more space and secure digital data protection while being able to carry around their sensitive files wherever they go.
  Firstly, since they're not built into computers, external hard drives always come at a lesser price than their integrated counterparts.
And since they can take up as much space as they want, they usually come with higher capacities because these high capacities are not possible inside laptops or desktop computers.
Capacities like 1 or 2 TB are common nowadays and these capacities are widely sufficient for everything you could want to put in there, even for a lot of backups if you like to keep your system backed up.
  The higher-capacity models are of course bigger than others and mostly conceived to be left standing on a desk where they can look beautiful and where they do not need to be moved around all day.
However, using such a device as a portable data storage is easier with the smaller models which feature between 200GB and 750GB which is still plenty for you to store music, movies and other stuff on, but these are small and light enough to be carried around in bags or pockets to be available whenever you need them.
  Going for a smaller drive is obviously the way to go if you work mostly with documents and pictures since these types of files do not need much hard disk drive space.
Whatever you need it for, an external hard drive is a wonderful way to work on your important projects from every place, no matter where you are, no matter what time it is.
   With the information revolution and all the wonderful advantages this brings, one of the most important factors for everyone with a computer is storage, because our internal hard drives are just not meant to hold hundreds of movies and pictures.
Specially storage-hungry files like games and movies can therefore easily be put on an external hard drive where they don't obstruct your internal hard drive.
This way you can save disk space and have everything in one place where it is easy to find it should you ever need to search for something.
