We all know that space is relative. First, it is relative to the size of the subject to whom it relates. For example, when you are young, everything looks bigger and vaster. The same reasoning applies when it comes to computer. Old users know what I’m talking about. Ten years ago nobody needed 100 GB HDD because there were no files as large as in the present. Now, it became harder and harder to get space, especially when you have to transfer the files from one place to another, from work to home or vice versa. The flash sticks are good but they are limited in space and time so, what other choice do we have?
