A method for improving redundant array of inexpensive disks 1 (RAID 1 array) reading efficiency, which includes providing a disk head address of each disk in a RAID 1 array; receiving a read command and providing a reading file address of the read command; choosing a first preferred disk from the disks in the RAID 1 array, which has a disk head address closest to the reading file address among disks of the RAID 1 array; and sending the read command to the first preferred disk.
