A write cache operation builder for use in building a write operation for writing data from a cache to a disk drive in a computer system is disclosed. The write cache operation builder is built from a CMS of a DASD. It converts the CMS entries of the CMS into a FIFO entry and scans the FIFO entry in order to calculate a write operation comprising the largest number of sectors of data. The write cache operation builder may be implemented via hardware or software.
