level where user data and redundant information (consistency) is striped across the physical disks in a . The equivalent of one physical disk's worth of capacity is used for redundant information. This RAID level is best used for applications such as multimedia or medical imaging that write and read large sequential chunks of data. If a single physical disk fails in a RAID 3 disk group, all associated become but, the redundant information allows the data to still be accessed. Any two-physical disk failure in the same disk group causes associated virtual disks to fail and data loss.
