What is a raid array

RAID allows you to combine multiple hard drives into an array. Typically, this will serve two purposes: redundancy, and creating a sort of Voltron super-drive. The two most widely used RAID array types are known as RAID-1 and RAID-0. A RAID-1 array will treat two or more hard drives as if they were the exact same drive. Raid contains groups or sets or Arrays. A combine of drivers make a group of disks to form a RAID Array or RAID set. It can be a minimum of 2 number of disk connected to a raid controller and make a logical volume or more drives can be in a group. Only one Raid level can be applied in a group of disks. Raid are used when we need …Because of this factor, RAID 10 requires at least four disks: two for a mirror, and a pair of those mirrors. What we get is an array with speed like a RAID 0 but benefits from the internal redundancy of a RAID 1. A RAID 10 array would only fail when one of the internal RAID 1 arrays fails. In each RAID 1 pair (or multiple-mirror if an admin so ...RAID is the way of combining several independent and relatively small disks into a single storage of a large size.
