RAID 5 – Block and Parity Stripe

RAID 5 organizes block data and parity data across the physical drives.
Generally, RAID Level 5 tends to exhibit lower random write performance due to
the heavy workload of parity recalculation for each I/O. RAID 5 is generally
considered to be the most versatile RAID level

Figure 3. RAID 5 Stripes all drives with data and parity information

The capacity of a RAID 5 disk array is the smallest drive size multiplied by the
number of drives less one. Hence, a RAID 5 disk array with (4) 100 GB hard
drives will have a capacity of 300GB. A disk array with (8) 120GB hard drives and
(1) 100GB hard drive will have a capacity of 800GB.

RAID 5 requires a minimum of three physical drives and a maximum of 16.
