Chapter 5: Disk Array Concepts

RAID 5 (Block and Parity Striping)

RAID 5 calculates parity in order to achieve redundancy rather than writing a
second copy of the data, like RAID 1. Parity is distributed across the physical
drives along with the data blocks. In each case, the parity data is stored on a
different disk than its corresponding data block. RAID 5 makes efficient use of
hard drives and is the most versatile RAID Level. It works well for file, database,
application and web servers.

Figure 4. RAID 5 Stripes all Drives with Data and Parity Information.

The capacity of a RAID 5 array is the smallest drive size multiplied by the total
number of drives, less minus one. Hence, a RAID 5 array with four 100 GB hard
drives will have a capacity of 300 GB. An array with two 120 GB hard drives and
one 100 GB hard drive will have a capacity of 200 GB.
