RAID data storage is quite a popular technique for preserving and accessing considerable quantities of information. Many RAID applications are used on computer servers, even though there are a number of amounts that may be used for desktop applications too.
Within this guide we’ll look at what precisely RAID is, what it will and also the benefits and pitfalls of working with this technology.
What is RAID?
RAID is an acronym for Redundant Array of Independent Disks. The technique was devised in the late 1980s and is still used today. Essentially, RAID is a method for multiple disc drives to work together and introduce themselves into a working system as one information storage medium.
RAID has basically 3 goals, to enhance the performance capacity of a server or computer, to boost the storage capacity of said computer and also to enhance the dependability of the data saved on it.
Various degrees of RAID achieve these three goals into a lesser or greater degree depending upon the Storage System that is used.
RAID utilizes a few fundamental data storage methods to realize its goals. The 3 standard data storage methods are mirroring, striping, and parity.
Mirroring is the process of earning the same copy of a set of information and saving it on more than one disk drive. This provides information redundancy, which protects your data by making it feasible to recover the information from another drive on your system in the event the initial hard disk fails for any reason.
Striping is the procedure of allocating information among different drives in the computer system. Striping evenly distributes information on every one of the drives which lets you get the information faster.
Parity is a method that permits you to rebuild blocks of information in case of a drive failure. Every degree of RAID utilizes these techniques in various techniques to reach the frequent goal of greater capacity, speed and reliability.
