In computing, a removable media is a data storage media that is designed to be readily inserted and removed from a system.[1] 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,[2] 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.[3] 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:
- Optical discs, e.g. Blu-rays (both standard and UHD versions), DVDs,[4] CDs
- Flash memory-based memory cards, e.g. CompactFlash, Secure Digital, Memory Stick
- Magnetic storage media
- Floppy and Zip disks (now obsolete)
- Disk packs (now obsolete)
- Magnetic tapes
- Paper data storage, e.g. punched cards, punched tapes (now obsolete)
Examples of removable media that are standalone plug-and-play devices that carry their own reader hardwares include:
- USB flash drives[5]
- Portable storage devices
- Dedicated external solid-state drives (SSD)
- Enclosured mass storage drives, i.e. modified hard disk drives (HDD)/internal SSDs
- Peripheral devices that have integrated data storage capability
- Other external or dockable peripherals that have expandable removable media capabilities, usually via a USB port or memory card reader
- USB hubs
- Wired or wireless printers
- Network routers, access points and switches
Using removable media can pose some computer security risks, including viruses, data theft and the introduction of malware.[6]
