Young ones these days will probably be surprised to know portable hard drives before came in the form of an 8-inch disk drive. And with the storage capacity of 256 KB! They increased it though when they came up with the smaller 5.25 inch version whihc could hold up to 360 KB of memory! Woohoo!

A little floppy history 

A floppy disk is a disk storage medium composed of a disk of thin and flexible magnetic storage medium, readable by a floppy disk drive (FDD), and sealed in a rectangular plastic carrier lined with fabric which serves the purpose of keeping the data storage disk free of foreign particles such as dust. The floppy disk was a revolution in the computer industry when it was developed by IBM in the late 1960s as a reliable and inexpensive method of loading microcode into their System/370 computer. Floppy disks remained a popular portable digital-storage medium for nearly 40 years after being introduced commercially in 1971.

Throughout the period in which floppy disks were common, they went through numerous improvements, each time significantly improving their available storage capacity and reducing their physical size as computer data storage technology advanced. Sizes ranged from 8 inches in the first commercialized floppy disk to the 3 1/2-inch floppy disks still available today.
