Figure 18 Raid 3 Multiple Drives Stripe Data with One Parity Drive
RAID 5 – Block and Parity Striping
RAID 5 is similar to RAID 3 as described above except that the parity data is rotated
across the physical drives along with the block data. Having the parity data striped
across all the physical drives in this manner removes the random write performance
bottleneck of RAID 3. The total capacity of a RAID 5 array is calculated the same as a
RAID 3 array.
