Abstract
Systems and methodologies are disclosed for interfacing a storage medium with a host using a segmented buffer. Data blocks are transferred between the host and medium according to logical block addresses, with buffer segment pointers indicating the logical block addresses of data blocks in the buffer. Buffer management hardware or firmware compares the pointer values directly with logical block addresses from host commands in order to determine whether desired data blocks are within the buffer.
