The data organizer circuitry organizes read/write data for read/write communication with the disk drive subsystems via the error circuitry such that the overall system appears as a large, high capacity disk drive system having an unusually high fault tolerance and a very high bandpass. Caching is additionally provided in the read/write interface in a manner which takes advantage of the organization provided by the data organizer to significantly improve overall performance. Advantage is also taken of the conventionally provided error detection capability of each disk drive subsystem to enhance the capability of the error circuitry. | |
