Removable media
In computing, a removable media is a data storage media that is designed to be readily inserted and removed from a system. Most early removable media, such as floppy disks and optical discs, require a dedicated read/write device (i.e. a drive) to be installed in the computer, while others, such as USB flash drives, are plug-and-play with all the hardware required to read them built into the device, so only need a driver software to be installed in order to communicate with the device. Some removable media readers/drives are integrated into the computer case, while others are standalone devices that need to be additionally installed or connected.
Examples of removable media that require a dedicated reader drive include:
Examples of removable media that are standalone plug-and-play devices that carry their own reader hardwares include:
Using removable media can pose some computer security risks, including viruses, data theft and the introduction of malware.
The earliest form of removable media, punched cards and tapes, predates the electronic computer by centuries, with the Jacquard loom of 1801 using interlinked cards to control the machine. This followed a loom made by Basile Bouchon in 1725 that used paper tape for its instructions. Punched tape was later used in Colossus, the first electronic computer.
Magnetic tape was developed in the early 20th century in Germany, based on magnetic wire recording invented by Valdemar Poulsen in 1898. In 1951, the UNIVAC I was released, using magnetic tape to store data. 8-inch floppy disks were commercially introduced in 1971 by IBM, with them being compacted to 5+1⁄4-inch by Shugart Associates in 1976. At the same time Compact Cassettes started being used to store data, being popular in the late 1970s and 1980s for holding data for personal computers. In 1982, the 3+1⁄2-inch floppy disk became commonplace, with its introduction for the Apple Macintosh and Amiga.
The CD-ROM was introduced in 1985, providing much higher capacity than a floppy disk, however could not be written to. This was resolved in 1990 with the introduction of the CD-R. The CD-RW, introduced in 1997 allowed the CD to be written to multiple times, rather than just once, as with the CD-R. DVD versions of these formats introduced in the late 1990s provided further increases in capacity. Additional capacity improvements were achieved with Blu-ray in 2006.
The turn of the millennium saw the widespread introduction of solid-state removable media, with the SD card being introduced in 1999, followed by the USB flash drive in 2000. The capacity of these removable flash drives improved over time, with 2013 seeing Kingston unveiling a 1 terabyte USB flash drive.
