RAID 53
High Input/Output Rates and Data Transfer Performance
RAID Level 53 requires a minimum of 5 drives to implement.
- 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
- 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
