Abstract
A method for reducing the number of I/O requests required to write data to a disk drive of a computer system. The computer system includes a read cache for storing old data read from the disk drive, and a write cache for storing new data to be written to the disk drive. The method selectively merges old data in the read cache with new data in the write cache to form at most two physically contiguous data segments which can be written to the disk drive with at most two I/O requests.
