There are 2 differents RAID mode:

RAID 0: RAID 0, known as disk striping, has generally
the best performance, but does not offer any redundancy.
In this level, data is broken into small units called sectors,
and sectors are distributed across all disks in the array. As
it does not provide any data protection, if any disk in the
array fails then all data in the array is lost. Such stripes
allocation allows to enhance I/O performance.
 RAID 1: RAID Level 1, known as disk mirroring, is a
popular approach to protect data from adisk failure. To
implement RAID Level 1, you need at least two physical
hard drives. As the disks are paired up, all disk writes are
duplicated on both disks. You can back up data without
interruption using this algorithm. In case of a disk failure,
the system can continue to run without being affected.
