RAID 5:
RAID 5 is the ideal solution for maximizing Disk space and Disk redundancy.
we're writing to 3 disks at a time for the SAME data, which means we're using up I/O bandwidth and not getting a real boost out of it.  This is the ultimate use of RAID 5.

Here are some of the details about RAID 5:

independent distributed parity block of data bits.
Minimum requirement == at least 3 drives ato be implemented.
Read Rate: Highest Data transaction.
Write Rate: Medium Data Transaction.
Transfer Rate: Good Cumulative.
RAID 5 is in expensive but very convenient. Parity info is stored in different disks.
If one disk fails then we can restore the data from back up.
