A method, computer system and apparatus describe how a data transmission rate of incoming and outgoing data are correlated to the size of a data storage area of a medium by formatting the medium with the data storage area into a plurality of sectors according to the data transfer rate of the data. The medium is correlated to a data transmission rate of data by providing a controller to format the medium into a sector size according to a packet size associated with the data transfer rate of the data. The method includes providing a controller with a capability of determining a read/write transmission size, the read/write transmission size correlated to the data transmission rate and the sector size. The controller also has the capability of determining a read/write transmission size according to the formula: Rtrans=(RHD, Rdata)max . The method includes formatting a hard disk drive, wherein the correlating the size of a data storage area on the hard disk drive with a data transfer rate includes correlating sector sizes of the hard disk drive according to a size of data packets to be transferred to the hard disk drive. The method includes providing an adaptive disk cache, the disk cache adaptively organizing the data into the size of the data storage area. The adaptive disk cache arranges the data for the data storage area such that a plurality of pending data requests can be reordered to complete the pending data requests efficiently.
