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. [8]
Audio tape cassettes and high-capacity floppy disks (e.g., Imation SuperDisk), and other forms of drives with removable magnetic media, such as the Iomega Zip drive and Jaz drives, are now largely obsolete and rarely used. There are products in today's market that will emulate these legacy drives for both tape and disk (SCSI1/SCSI2, SASI ...
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 ...
Many types of malware copy themselves to removable storage devices: while this is not always the program's primary distribution mechanism, malware authors often build in additional infection techniques. Examples of malware spread by USB flash drives include: The Duqu collection of computer malware. The Flame modular computer malware.
File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books.
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]
For example, SSDs store data using multiple NAND flash memory chips. The first NAND-based removable memory card format was SmartMedia , released in 1995. Many others followed, including MultiMediaCard , Secure Digital , Memory Stick , and xD-Picture Card .
