Abstract：
 A method for optimizing IO performance of adaptive external storage device includes requesting to distribute priority for IO arrived at external storage device driving program and inserting it into IO request processing queue, obtaining statistic data of IO access address increment and preprocessing obtained data, calculating access address of preread data by utilizing said statistic data, calculating size of preread data starting from access address of preread data and from data used by external storage device to fetch preread data size to data buffer-storage.
