RAID is used to combine the space of multiple drives in order to
increase the storage space performance or stability. A RAID can
consist of 2 or more drives and can be used in one of two
RAID 0: Striping
This RAID mode is designed for speed. It does not have any fault
tolerance or data protection. At least two drives are required for this
mode. If one drive in RAID 0 were to fail, then there would be no way
to recover data.
RAID 1: Mirroring
This RAID mode is designed for data integrity and fault tolerance.
This mode is not as fast as RAID 0. However, RAID 1 uses the second
drive (target drive) as a copy of the first drive (source drive).
Solutions for environments that require the use of multiple hard drives.
