50. sk Array in which part of the storage capacity is used to record redundant information about the user data stored on the remainder of the storage capacity The redundant information enables regeneration of user data in the event that one of the Array s member Disks or the access path to it fails Benefits of RAID 1 Secure Data RAID is an emerging storage technology with the potential to revolutionize the data storage technology A typical RAID unit contains a set of disk drives typically two to six which appear to the user to be equivalent to a single large capacity disk drive The remarkable benefit of disk array is that if any single disk in the RAID fails the system and array still continues to function without loss of data This is possible because the redundancy data is stored on separate disk drives and the RAID can reconstruct the data that was stored on the failed disk drive 2 Increases system performance As the effective seek time for finding data on a disk can potentially be reduced by allowing multiple simultaneous access of different data on different disks Utilizing parallel reads and writes of the data spread across the disks in the array the data transfer rate can be increased significantly over that of a single disk 3 Easy maintenance RAID system maintenance is typically simplified because it is easy to replace individual disks and other components while the system continues to function Hot swap support Introduc
