Which of the following RAID implementation types features disk striping and a dedicated parity drive?
  1. RAID-0
  2. RAID-1
  3. RAID-3
  4. RAID-5
Explanation
Answer - C - RAID-3 features disk striping and a dedicated parity drive to provide fault tolerance.

Key Takeaway: With RAID-3 implementation, data is striped across multiple disks at a byte level. The exact number of bytes sent in each stripe is less than 1024. The parity information is sent to a dedicated parity disk, but the failure of any disk in the array can be tolerated. The dedicated parity disk serves as a performance bottleneck, especially for random writes, because it must be accessed any time anything is sent to the array.
