RAID technologies, which stands for redundant array of independent disks, continues to be a mainstay in the IT sector for some time now. In most cases, RAID combines multiple disk drives into a single unit, and information is divided, replicated, and distributed across the drives, basically for greater storage space.
A RAID device holds multiple drives at once, and allows you to buy drives as you want them. With traditional RAID you are locked into particular”RAID levels,” (that in layman’s terms, is simply different array architectures offering various benefits concerning data availability, cost, and functionality ) and so as to alter them, most storage arrays ask you to move data from the drive, reconfigure the drive, and then move it forth.

Traditional RAID also entails lack of expandability: after drives are configured into a RAID pool that is it. If you would like to add more storage capacity, the remedy is to create a new RAID pool, which probably means starting over. And a third drawback regarding traditional RAID concerns drive failure:
When a drive fails, many RAID applications of hard disk enter a country where data reduction will occur if a different drive falters until the consumer replaces the failed drive-again, leaving the consumer no opportunity to save his documents before they are lost. Also, performance is influenced when in this state.
The volume of information that firms and people are going to need to manage is always expanding. The days of knowing how much storage capacity you will need prior to buying a driveway are disappearing. Information updates so often that information storage capability has to be able to conform to the demands of the user.
This on-demand demand for information storage requires for greater external drives. If you would like to add storage capability, they should allow you to just insert additional disk drives or substitute smaller discs with ones which have more capacity and automatically reconfigure.
