Redundant Array of Indipended Disk ( RAID) explanation in terms of Failure, Perfomance and Redundancy

Question

How would you explain RAID in terms of Failure , Perfomance and Redundancy?

Answer 1

Hello,

There mainly two types of RAID hardware RAID and software RAID.

Below is the useful article from Microsoft whch explain different type of RAID levels with performance, redundancy..etc.

Hope this helps.

Hi again,

Simply,

RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives to protect data in the case of a drive failure.

Redundancy means that your system contains duplicate copies of a file. In the event of a failure you have another available copy to work with which is great if you can't afford to lose any of your files.

RAID provides a performance boost by dividing data into blocks and spreading them across multiple drives using what is called disk striping. By spreading data across multiple drives, it means multiple disks can access the file, resulting in faster read/write speeds
