Abstract
Data coherence checking apparatus, a redundant array of independent disks (RAID) controller and a storage system having the checking apparatus and a method therefor are proposed. The present invention employs an XOR operation unit and an OR operation unit to check the coherence of data to be checked. The XOR operation unit is used to perform XOR operation on the data to be checked. After the XOR operation unit finishes performing the XOR operation on the data of a processing set, it outputs an XOR operation result to the OR operation unit to perform OR operation so as to obtain a check result.
