Abstract
A method and apparatus is disclosed for partitioning a data buffer to create separate read and write buffers, wherein the boundaries between the buffers and the sizes of the buffers change dynamically depending upon the command mix received from the host computer. Data buffer space is allocated to provide highest priority to processing the current host command, and next priority to preserving a read ahead cache.
