Abstract
A method for synchronously writing data from memory to a disk drive memory device minimizes the number of actual I/O operations by writing data to disk in large chunks. The method comprises the steps of: allocating an array for saving buffer pointers; mapping the data to the disk space; allocating a buffer for each block of disk space; copying the data into the buffer; saving a pointer to the buffer in the array and then writing physically adjacent blocks to disk in one I/O operation. The method also updates and reads address blocks in the buffer pool and writes them to disk only at the end of the write request.
