Types of Storage Devices Physical components or materials on which data is stored are called storage media. Hardware components that read/write to storage media are called storage devices. Two main categories of storage technology used today are magnetic storage and optical storage. Primary magnetic storage o Diskettes o Hard disks (both fixed and removable) o High capacity floppy disks o Disk cartridges o Magnetic tape Primary optical storage o Compact Disk Read Only Memory (CD ROM)

Data stored in backing storage is permanent so it is NOT lost when the computer is turned off. It is always slower to access data from backing storage than from internal memory.

Cloud storage is a model of networked online storage where data is stored on multiple virtual servers‚ generally hosted by third parties‚ rather than being hosted on dedicated servers.Hosting companies operate large data centers; and people who require their data to be hosted buy or lease storage capacity from them and use it for their storage needs. The data centeroperators‚ in the background‚ virtualize the resources according to the requirements of the customer and expose them as storage pools

define at least five different types of storage devices from the most reliable to the least reliable. Include in your search cost and availability of the storage devices. Include names of vendors for these storage devices. There are three main types of consumer-grade computer storage: internal‚ external‚ and network attached. Internal storage is generally a hard drive or solid-state drive (SSD) that hosts computer’s operating systems and programs. External storage comes mostly in the form of external

The need for more storage is growing. The amount of data produced is doubling in every two years. (in 2010 – 1.8 zettabytes) The cost of creating‚ managing and storing the data is decreasing‚ but can the optical storage expand further? The current Blu-ray lasers emit light in the blue part of the electromagnetic spectrum (about 420 nanometer wavelength). There are ongoing researches using UV light‚ that would probably have to be 200 nm and would provide storage capacities of over 100 GB in a single
