RAID stands for redundant array of independent disks. So, basically, you have to have more than one physical hard drives for RAID to make any sense. You want to configure several hard disks in RAID when you want to enable redundancy for disaster management, or to improve performance of your system. In plain English, when you have RAID configuration, if one of hard disks dies, your data is safe, because RAID made exactly the same copy of your hard disk on one of the other hard disks.
@Kainui see chapter 6 in that book
6.2
RAID actually is an acronym for Redundant Array of Inexpensive Devices. There are several "levels" of RAID. Most keep your data in such a way that it can be recovered if one of the RAID drives fails. Most of the RAID levels store the data in a way that can be rebuilt in case of failure, takes a while, but you don't lose anything.
