RAID is a technique of data or file recovery which accomplishes a single
drive, which in turn contains multiple drives. RAID data recovery files
are of different levels. Different levels are applied for application
depending on the speed of access and size of the files. Each level has
different capabilities. A level generally has many drives and RAID array
controller.
Here the multiple drives are arranged logically in such a way that the
files are spread among the multiple drives.
