In an example embodiment, an adaptive method of prefetching data blocks from an input/output device comprises predicting the address of each read operation reading a data block from the input/output device, the prediction based on the address of the immediately preceding read operation from the input/output device; tracking, for each read operation, whether each read operation reads a block data from the same address of the input/output device predicted for the read operation; and prefetching a data block for a read operation from the input/output device in accordance with the state of a state machine, the state of the state machine depending upon whether immediately preceding read operations read a data block from the same address of the input/output device predicted for the read operations.
