RAID Configuration The introduction of RAID levels and types are as below: RAID 0 breaks the data into blocks which are written to separate hard drives. Spreading the hard drive I/O load across independent channels greatly improves I/O performance. RAID 1 provides data redundancy by mirroring data between the hard drives and provides enhanced read performance. RAID 5 provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. RAID 10 uses four hard drives to create a combination of RAID 0 and 1 by forming a RAID 0 array from two RAID 1 arrays.

RAID Configuration
The introduction of RAID levels and types are as below:
RAID 0
breaks the data into blocks which are written to separate hard drives.
Spreading the hard drive I/O load across independent channels greatly
improves I/O performance.
RAID 1
provides data redundancy by mirroring data between the hard drives and
provides enhanced read performance.
RAID 5
provides data striping at the byte level and also stripe error correction
information. This results in excellent performance and good fault tolerance.
RAID 10
uses four hard drives to create a combination of RAID 0 and 1 by forming a
RAID 0 array from two RAID 1 arrays.
