Redundant RAID Level where user data and redundant information (parity) is striped across the drives in an array. The equivalent of one drive'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 drive fails in a RAID 3 array, all associated logical drives become degraded but the redundant information allows the data to still be accessed. Any two-drive failure in the same array causes associated logical drives to fail and data loss.
