Abstract
In a write process of compressed data #1, data transfer for one sector from a CPU to an HDD, and a local write for one sector by the HDD repeat themselves for 256 sectors. During the write process period, the system BIOS compresses data of the next data block by utilizing the period in which a local write is made by the HDD. That is, upon completion of data transfer for one sector, the system BIOS waits for completion of the local write for one sector by the HDD, and then transfers the next data for one sector. During that local write completion wait period, the system BIOS compresses the next data.
