description The embodiment of the invention relates to the technical field of hard disks, and provides an RAID function implementation method and a related device. The method comprises the following steps: receiving to-be-written data sent by a host and a to-be-written address of the to-be-written data on a hard disk, wherein the to-be-written data and the to-be-written address are determined after splittingto-be-stored data according to a mapping relationship pre-stored by the host and a logic address of the to-be-stored data, and the pre-stored mapping relationship is generated according to RAID configuration information read by the host from the hard disk and adjacent member disk information; and writing the to-be-written data into the hard disk according to the to-be-written address. According tothe embodiment of the invention, the RAID configuration information can be provided through the hard disk, the host performs data distribution according to the RAID configuration information providedby the hard disk, the hard
