Abstract
In accordance with the invention, a system and method for further enhancing the transfer efficiency of the disk is provided. In an aspect of the invention, a hierarchical data structure for storing a portion of data in a data file is provided. The data structure includes a granule storage unit that is configured to store individual bits of data, a randomly sized component data unit that is configured to group a sequence of granules as a related data unit, and an extent transfer unit that is configured to group at least one component data unit as a data file. The granule storage unit may include at least one header granule and at least one data granule. The header granule includes metadata information relating to the component data unit.
