DATA DATA DATA DATA DATA Reads can occur simultaneously on every drive RAID 3 sector stripes data across groups of drives but one drive in the group is dedicated to storing parity information RAID 3 relies on the embedded in each sector for error detection In the case of drive failure data recovery is accomplished by calculating the exclusive OR XOR of the information recorded on the remaining drives Records typically span all drives which optimizes the disk transfer rate Because each 1 0 request accesses every drive in the array RAID arrays can satisfy only I O request at a time RAID delivers the best performance for single user single tasking environments with long records Synchronized spindle drives are required for RAID 3 arrays in order to avoid performance degradation with short records RAID 5 arrays with small stripes can yield similar performance to RAID 3 arrays Read and write operations span all drives Y ov v DATA DATA DATA DATA DATA PARITY Paralled access decreases data transfer time for lana seauential records Under RAID 5 parity information is distributed across all the drives Since there is no dedicated parity drive all drives contain data and read operations can be overlapped on every drive in the array Write operations will typically access one data drive and one parity drive However because different records store their parity on different drives write o
