Abstract
A system and method for updating partial blocks of file data stored in a non-volatile storage within a file cache system connected to a host computer system. A first buffer and a last buffer receive from the non-volatile storage the existing portions of the blocks that are to be retained. A write buffer receives new data of a size not equal to an integral multiple of a block from a host computer system. The new data is merged under hardware control with the existing portions contained in the first buffer and the last buffer, thereby updating the cached file.
