Storage devices are used to record or retrieve data in technological devices. A device that only records information is called a recording medium; it does not allow for processing of the information. They allow for ease of access for the user to retrieve any data from the device that had been previously stored. They help run programs, view page content, and even allow for interaction on some web pages. There are two types of storage in computers; a primary storage, like RAM, or Random Access Memory, and a secondary storage, like a hard drive. Without storage devices, computers would not function as efficiently as they do.

Hard Disk Drive (Hub Pages)
Magnetic disks are the preferred storage for computers. They are what house the data on storage devices such as hard disks, flash drives, and floppy disks. The disks, or platters, are made from a material that is not magnetic, usually aluminum alloy, glass, or ceramic, and are coated with a thin layer of magnetic material. This allows for only the manipulation of the magnetic material, rather than the manipulation of the whole disk. The head of the storage device then reads the magnetic transitions to know which data to retrieve or process. This is how the information shows up on the computer screen. (escotal.com)
The downfall of having information stored on magnetized devices is that they may easily be corrupted or erased. Data corruption can happen from common user mistakes such as improper shutdown or ejection, or things that may be out of the user’s control such as power outages or computer viruses (The X Lab). It is very difficult and sometimes impossible to recover lost or corrupt data from a hard disk drive, external or internal. To avoid corruption or loss of data, proper shutdown and ejection of the device is crucial. Also, backing up devices saves a lot of time and headaches. It is a method to ensure you do not loose important information that may otherwise be lost in power outages or from a computer virus.
An external hard drive, or disk, is a storage device than can connect to your computer to allow for more storage of data than your current hard disk allows. They can be removed easily, but can only be accessed if...
