The ways of saving your documents, pictures, videos, etc. have changed a lot over time. So, lets go back to where it started.

First, came the card. Early computers often used punch cards for input both of programs and data. Until the 1980's these cards we very commonly used for computer data saving. They were used as early as 1725.

Next came the desktop hard drive. The first hard drive was the IBM Model 350 Disk File that came with the IBM 305 RAMAC computer in 1956, with a total storage capacity of 5 million characters.

Third, we have the 5 1/4 inch floppy disc. A floppy disc is a portable computer storage device that permits easy handling of data. Well, at least at the time. When a disk is inserted into the disk drive of a computer, information can be magnetically imprinted on this coating which will there after permit easy location and retrieval of the same data.

Now we have the 3 1/2 inch floppy disc. Once the standard medium of data transfer, the 3 1/2" floppy disk suffers from the reputation of being obsolete.

Number 5 is the disc. The diskette, or floppy disk (named so because they were flexible), was invented by IBM and in common use from the mid-1970s to the late 1990s.

Last is the Thumb Drive. USB flash drives are NAND-type flash memory data storage devices that connect to a computer through a USB interface.
