RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. It requires a minimum of four disks and stripes of data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. If two disks in the same mirrored pair fail, all data will be lost because there is no parity in the striped sets. RAID, which stands for redundant array of independent disks, comes in several different configurations. A RAID 1 configuration copies data from one drive to another, mirroring and duplicating data to provide improved fault tolerance and data protection. Data is fully protected as the mirror copy is available if the originating drive is disabled or unavailable. Because it makes a full duplicate of the data, RAID 1 requires twice as much storage capacity as the original data. RAID 0 doesn't provide any data protection; its sole purpose is ...
