RAID Configuration (optional)
RAID Configuration (optional)
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.
