RAID 53: High I/O Rates and Data Transfer Performance 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 |
