Requirements

• RAID Level 53 requires a minimum of 5 drives to implement

Characteristics/Advantages

• RAID 53 should really be called "RAID 03" because it is implemented as a striped (RAID level 0) array whose segments are RAID 3 arrays
• RAID 53 has the same fault tolerance as RAID 3 as well as the same fault tolerance overhead
• High data transfer rates are achieved thanks to its RAID 3 array segments
• High I/O rates for small requests are achieved thanks to its RAID 0 striping
• Maybe a good solution for sites who would have otherwise gone with RAID 3 but need some additional performance boost

Disadvantages

• Very expensive to implement
• All disk spindles must be synchronized, which limits the choice of drives
• Byte striping results in poor utilization of formatted capacity
