What Does RAID 2 Mean?RAID 2 is another RAID standard level configuration that provides very high data transfer rates. In RAID 2, a central controller synchronizes the disks by making them spin at the same angular orientation so that they all reach the index simultaneously. RAID 2 uses bit-level striping and each sequential bit is placed on a different hard drive. The error correcting code (ECC) used is the Hamming code parity, which is calculated across bits and stored separately in at least a single drive.
RAID 2 is one of at least nine types of RAID.
