One example of malware that propagates through removable media such as USB flash drives is Stuxnet, which caused significant damage to Iran's nuclear program. The risk from an attack like this can be reduced by automatically scanning media for malware and prohibiting users from attempting to access the contents of removable media of unknown origin.
In the 1964 removable disk media was introduced by the IBM 2310 disk drive with its 2315 cartridge used in IBM 1800 and IBM 1130 computers. [7] Magnetic disk media is today not removable; however disk devices and media such as optical disc drives and optical discs are available both as internal storage and external storage.
As a result of having no moving mechanical parts, solid-state storage has no data access latency required to move the media as in an electromechanical storage device. This allows for significantly higher I/O operation rates . Additionally, solid-state storage consumes less power, has better physical shock resistance, and produces less heat and ...
Examples of such media include (a) magnetic disks, cards, tapes, and drums, (b) punched cards and paper tapes, (c) optical disks, (d) barcodes and (e) magnetic ink characters. Wikimedia Commons has media related to Computer storage media .
A typical USB drive is removable, rewritable, and smaller than an optical disc, and usually weighs less than 30 g (1 oz). Since first offered for sale in late 2000, the storage capacities of USB drives range from 8 megabytes to 256 gigabytes (GB [note 2]), 512 GB and 1 terabyte (TB [note 3]).
This is slightly different from a portable media player, which is designed to only store music and video files that its internal reader softwares can play. Most modern PSDs are dedicated solid-state drives (SSD) that are connected to a computer and powered via USB ports .
Notable types are hard disk drives (HDD), containing one or more non-removable rigid platters; the floppy disk drive (FDD) and its removable floppy disk; and various optical disc drives (ODD) and associated optical disc media. (The spelling disk and disc are used interchangeably except where trademarks preclude one usage, e.g., the Compact Disc ...
CD-ROMs are the most common forms of media used, but other media, such as magnetic or paper tape drives, ZIP drives, and more recently USB flash drives can be used. The computer's BIOS must support booting from the device in question. One can make one's own boot disk (typically done to prepare for when the system won't start properly). [2]
