Which RAID set stripes data with parallel access and dedicated parity disk

Which RAID set stripes data with parallel access and dedicated parity disk

• 5
• 0
• 3
• 6 

 

EXPLANATION

Raid 0 =  Striped data with no fault tolerance. Good for applications needing high I/O throughput
Raid 5 = Striped set with independent disk access and distributed parity. Dedicated drive parity writes can become bottlenecks, RAID 5 distributes them to avoid. Good for random, read-intensive I/O applications
Raid 6 =  Striped set with independent disk access and dual distributed parity. Includes second parity in case two disks fail. Write penalty is higher. Rebuild time is higher.
Raid 3 =  Striped set with parallel access and a dedicated parity disk. No partial writes to update one strip in a stripe
