In computing, mass storage refers to the storage of large amounts of data in a machine-readable. In computing, mass storage refers to the storage of large amounts of data in a machine-readable.
Contents
Types
Common types of mass storage include
Solid State Drive
The Solid State Drive (SSD) is a type of data storage device that uses non-volatile memory to store data, instead of the magnetic disks or disks of conventional hard disk drives.
Hard Drives
The hard disk drive is the data storage device that uses a magnetic recording system to store digital files. It consists of one or more plates joined by a same axis that rotates at high speed inside a sealed metal box. On each plate, and on each of its faces, there is a read / write head that floats on a thin sheet of air generated by the rotation of the discs. It is non-volatile memory.
External Hard Drives
An external drive is just a hard drive or solid-state drive that is connected to a computer on the outside rather than on the inside.
Optical drives
The optical disk unit is the disk unit that uses a laser light as part of the process of reading or writing data from a file to optical discs through beams of light that interpret the refractions caused on its own emission.
Tape drives
A tape drive is a storage device that reads and writes data on a magnetic tape. Magnetic tape data storage is typically used for offline, archival data storage. Tape media generally has a favourable unit cost.
RAID storage
RAID, Redundant Array Independent Disks is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement.
USB
The USB (Universal Serial Bus) is accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an external hard drive.
Flash Memory Card
A flash memory card is a small storage device that uses nonvolatile semiconductor memory to store data on portable or remote computing devices.
Evolution
Prices in the market
The traditional hard disks have not stopped offering any more and better services since its journey began on the market, and nowadays the capacities and prices of these units have gone fitting up to coming at a level in which the cost for GB is almost ridiculous.
This way, a unit of 2 TB of Digital Western can be for 89,99 dollars in the United States, and that gives a cost for 0,043 dollars for GB. Or what is the same, scarcely 3 cents for GB, a number that makes clear the complex margins in which these units move.

- Depending on the type of storage be already the brand, the size of storage or the configuration of the same one as safety copies the price can change.
