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.

1. A RAID device with command processing and data transmission adapting ability comprising: at least one hard disk; and, a RAID controller connected to a host computer through a bus, said RAID controller including at least: a command register connected to said bus through a selection switch for temporarily storing commands issued from said host computer; a data hub connected to said bus through said selection switch, said data hub selectively passing only the data to be accessed; at least one hard disk driver connected to said command register and said data hub, said hard disk driver being coupled to said hard disk; and, a controller connected to said selection switch, said command register, said data hub, and each said hard disk driver for the control thereof in selectively establishing a data transmission channel defined between said host computer and said hard disk for the direct passage of data therebetween; said controller processing said command and regulating channel for data transmission. 2. The RAID device as in claim 1, further comprising a data processing unit arranged between said data hub and each said hard disk driver. 3. The RAID device as in claim 2, further comprising an OR gate connected to each said hard disk driver. 4. The RAID device as in claim 1, further comprising a data register connected to said data hub for retrievably storing identifying information. 5. The RAID device as in claim 1, wherein each said hard disk driver can detect hot swap of a disk drive and inform said controller. 6. The RAID device as in claim 2, wherein said data hub and said data processing unit can transmit data directly from a hard disk drive to another hard disk drive without data buffering means. 7. The RAID device as in claim 1, wherein said selection switch is controlled by said controller to connect to one of said data hub and said command register.
