PROBLEM TO BE SOLVED: To provide an improved technology to transfer buffer data between a host and a data storage device. SOLUTION: In this architecture, it is provided with a host pointer, which links an extent record to a next host extent record in a host extent record set, and a storage device pointer, which links the extent record to a next storage device extent record in a storage device extent record set. In addition, a system to transfer data between a host and a storage device is provided. In the system, an extent table is related to the data buffer, and the extent table includes at least one extent record, an LBA chain table that is connected to the host and the extent table, and a track section table that is connected to the storage device and the extent table.
