Abstract
A RAID device has command processing and data transmission adapting ability. The RAID device comprises a RAID controller connected to a host computer through a bus, and a plurality of hard disks. The RAID controller comprises a controller, a selection switch, a command register, a data hub. The controller is connected to all other components of the RAID controller. The controller processes command and regulates channel for data transmission such that the data is directly accessed between CPU and storage disk. The buffer memory is saved and the data can be rebuilt to reduce the risk of computer failure.
