Storage Devices

Storage Devices store data in the computers. There are several types of storage devices for computers. These storage devices offer a wide range of storage options. Floppy devices store 1.44MB of data. Advanced storage devices store several gigabytes of data. The different types of storage devices are: 

Magnetic devices – Are the most common form of data storage. Magnetic devices like floppy devices, zip drives, and portable drives are highly popular forms of data storage devices. 

Optical devices– Provide large amount of data storage. The Compact Disk (CD) is the most common form of optical storage device. Optical devices are very compact and inexpensive. The PC reads data from optical devices with the help of a laser beam. 

Solid-State Storage devices– Use flash memory for storing data. Digital cameras and memory cards for video games are types of solid-state storage devices. These devices are very light and small in size. The speed of operation is high in solid-state storage devices. 

Digital Audio Tape – Digital Audio Tapes (DAT) provides a digital means of recording music. Digital music contains a huge volume of data. DAT uses a rotary head that rotates diagonally across the head of the tape. The rotary head records the music. As a result, we also call DAT by the name R-DAT, where R stands for Rotary.DAT provides superior quality and high speed of music recording. The DAT provides about 180 minutes of music on a single tape. DAT does not use data compression while recording.
