Over 50 years ago, IBM developed a hard disk that was the size of several wardrobes and had a capacity of only five megabytes. This was the very first hard disk. Today, hard disks the size of standard paperbacks with capacities of one terabyte (1,000,000 megabytes) or more are nothing out of the ordinary.
In the last 10 years, we have seen formats come and go in the storage scene, but if there is anything that is consistent, it is this: capacities increase, and form factors shrink. Here is an example to prove our point. 10 years ago, 5.25" hard disk drives breached the one gigabyte mark. Last year, Seagate announced a 3.5" hard disk with 1.5 terabytes capacity.
