Introduction to RAID
Overview of RAID
Redundant array of independent drives (RAID) is an array of multiple independent
hard drives that can be accessed simultaneously, improving I/O (input/output)
performance. The RAID array is recognized by the host computer as a single storage
unit or as multiple logical units. Data loss, because of a drive failure, can be
prevented for RAID 1 and RAID 1+0 by reconstructing missing data from the
remaining data drives.
