Storage Devices

Storage devices store data. The computer has many types of data storage devices. Some of them can be classified as the removable data storage devices and the others as the non-removable data storage devices. Data storage devices come in many sizes and shapes. The technology used for the storage of the data can be altogether different. Storage devices are some of the most important components of the computer system.

Memory comes in two variations. Primary memory is volatile and secondary memory is non-volatile. Volatile memory is the kind of the memory that is easily erased. Typically, this happens when the electricity is turned off. Primary memory, however, is fast. Information can be retrieved quickly so it is preferred by the processor when performing its operations. Non-volatile memory is the type where the contents cannot be so easily erased but is slower in retrieving data. It is therefore used for long term storage. So when we talk about data storage devices it is generally assumed to be those devices that employ secondary memory. These devices include:

Hard disk drives – This drive is large and is located inside the computer system. It is a permanent component of the computer. It is the most common type of storage device and is found in almost all computer systems.
