A data storage device is a device for recording (storing) information (data.) Recording can be done using virtually any form of energy. A storage device may hold information, process information, or both. A device that only holds information is a recording medium. Devices that process information (data storage equipment) may either access a separate portable (removable) recording medium or a permanent component to store and retrieve information.

Electronic data storage is storage that requires electrical power to store and retrieve data. Most storage devices that do not require visual optics to read data fall into this category. Electronic data may be stored in either an analog or digital signal format. This type of data is considered to be electronically encoded data, whether or not it is electronically stored. Most electronic data storage media is considered permanent (non-volatile) storage, that is, the data will remain stored when power is removed from the device. In contrast, electronically stored information is considered volatile memory Vision can refer to: Visual perception is one of the senses. ... It has been suggested that this article or section be merged into Analog electronics. ... A digital system is one that uses discrete numbers, especially binary numbers, or non-numeric symbols such as letters or icons, for input, processing, transmission, storage, or display, rather than a continuous spectrum of values (an analog system). ... An encoder is a device used to encode a signal (such as a bitstream) or data into a form that is acceptable for transmission or storage. ... A semiconductor is a solid whose electrical conductivity can be controlled over a wide range, either permanently or dynamically. ... Volatile memory refers to computer memory that must be powered to maintain its data. ...


With he exception of barcodes and OCR data, electronic data storage is easier to revise and may be more cost effective than alternative methods due to smaller physical space requirements and the ease of replacing (rewriting) data on the same medium. However, the durability of methods such as printed data is still superior to that of most electronic storage media. The durability limitations may be overcome with the ease of duplicating (backing-up) electronic data.

Terminology

Devices that are not used exclusively for recording (e.g. hands, mouths, musical instruments) and devices that are intermediate in the storing/retrieving process (e.g. eyes, ears, cameras, scanners, microphones, speakers, monitors, projectors) are not usually considered storage devices. Devices that are exclusively for recording (e.g. printers), exclusively for reading (e.g. barcode readers), or devices that process only one form of information (e.g. phonographs) may or may not be considered storage devices.

Data storage equipment

The equipment that accesses (reads and writes) storage information are often called storage devices. Data storage equipment uses either:

  • portable methods (easily replaced),
  • semi-portable methods requiring mechanical disassembly tools and/or opening a chassis, or
  • inseparable methods meaning loss of memory if disconnected from the unit.

The following are examples of those methods: A chassis (plural: chassis) consists of a framework which supports an inanimate object, analogous to an animals skeleton; for example in the construction of an automobile or of a firearm. ...

USB mass storage device class - Wikipedia, the free encyclopedia (921 words)
The USB mass storage device class is a set of computing communications protocols defined by the USB Implementers Forum that run on the Universal Serial Bus.
The USB mass storage as such does not specify which file system shall be used on the device using it; instead, it mainly provides a way of reading out sectors as on any hard disk device.
The mass storage interface is an attractive option for many devices, such as cameras and media players, which are nonetheless capable of more functionality than being simple data repositories.
Mass-storage device - Wikipedia, the free encyclopedia (257 words)
A mass-storage device is usually a very high capacity computer storage medium that is an order of magnitude less costly than a hard disk or other primary storage media.
In early computers, magnetic tape was the mass storage device of choice, offering essentially unlimited storage of data cheaply but with significant data recovery times, as it generally required a computer operator to recover the relevant reel from a tape store.
The floppy disk was the first mass storage device used in conjunction with a PC.
