- RAID 53 Should really be called "RAID 03" because it's 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 it's RAID 3 array segments
- High I/O rates for small requests are achieved thanks to it's RAID 0 striping
- Maybe a good solution for sites who would have otherwise gone with RAID 3 but need some additional performance boost

- 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
