As with levels 3 and 4, each of the sectors 1 through n-1 (n=S in this case) is accessed in a stripe set. The last sector is dedicated to storing the parity data. The next stripe set of blocks is skewed, placing the parity block on another drive; each drive has some parity blocks. The advantage here is that small write operations can acuer in parallel. For example, a write to logical sector 4 requires a physical write to drive 4 and drive S. A write operation to logical sector 26 requires a write operation to disk 2 and disk 3. These operations can occur simultaneously.
