Abstract
A multiple disk drive array storage device emulates the operation of a single disk drive. The array storage device includes a large buffer memory and a plurality of asynchronously-operating disk drives. A full physical track of data from each of the disk drives within the array is stored within the buffer memory and concatenated to create a large logical track of data. The large buffer memory and asynchronously-operating disk drives results in a data transfer rate that is faster than the standard disk drive architecture.
