23. Block and parity striping RAID 5 is useful for the performance gains offered from a striping array with the added security feature of single fault tolerance RAID 5 uses all drives to stripe data and also stripe parity data Since parity is calculated on the fly during write operations RAID 3 which uses a dedicated drive for parity experiences a performance bottleneck when the system constantly writes t parity data to a single drive Under RAID 5 parity is striped across all drives Parity calculation and data writes are much faster keeping all the drives in the array busy This vastly improves random write performance In a nutshell block and parity striping is best suited for those who wish to enjoy the performance advantages of a striping array but who require at least single drive fault tolerance Spanning In some instances spanning may be a preferred model of combining drives together rather than striping One reason that an array might be configured as spanning instead of striping would be to make full use of all the capacities of all drives in the array even if drives are mismatched in size With striping the array size is restricted to the number of drives times the storage capacity of the smallest drive This cuts off portions of any drives that are larger than the smallest The other reason that spanning might be considered over striping may be performance With striping the performance is affected directly by the strip
