From Floppy Disk to External Hard Disk

Fifteen years ago, a floppy disk was used to store data from a computer. The floppy disk was such a sensitive stuff that we had to look after it like taking care of a baby. Today, we don't even use the 3.5" floppy disk, let alone the thin 5 1/4 floppy. Our data/images/files/etc are now stored in a CD or DVD, USB Disk, or even an external hard disk.

Gone are the days we needed 10 pieces of 3.5" floppy disk to store a file of 15 MB in size. Dividing a single big file into several smaller size files is not necessary anymore, unless this file is gigangous. One 256 MB USB Disk today is enough to store many files. If this is not enough, buy an 80 GB laptop's external hard disk. It's small and convenient because it doesn't use up a lot of space, even it can be put in your pocket.

USB disk is very useful to move files from one computer to another. Its small size makes it very easy to carry, just put it in the pocket. The hard external case of USB disk can protect itself, too, unlike the old floppy disk. Meanwhile, an external hard disk is usually used for backing-up data/project of large size. If you have a long term project and you are in the final year of this project, you don't want to lose anything of whatever you've done.

There was a case recently when a researcher's laptop stolen by a theft, he lost all his project data, results, papers and all his colleagues' works stored in his laptop. He never made a back-up of the laptop's hard disk so he made a plea to the theft by advertising in a newspaper. The theft probably doesn't read newspaper at all.
