A data processing system including at least one storage device for storing and retrieving data from several rotating tracks where each track includes sequentially located blocks for the storage of data. A storage interface is connected for controlling this storage device. The storage interface includes a data buffer for storing data retrieved from the storage device. A storage driver is provided that receives storage access commands from a processor and provides commands to the interface in response to these commands from the processor. This storage driver further includes the capability to provide commands for requesting data that has not been requested by the processor. This data not requested by the processor is stored in a data buffer. These commnads for data not requested by the processor are issued in accordance to procedure that computes these commands called read ahead commands based on the order of commands received from the processor and also based on the number of storage devices in use.
