RAID Configuration
Below are the different types of a RAID.
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.
