Apparatus and method for operating a data processing system (10) having a data processor (12), a disk data storage subsystem (14), and a disk manager (16). The method includes the steps of (a) partitioning the disk data storage system into multiple partitions including a first partition (28) and a second partition (30); (b) managing at least the first partition as a log-structured file system (LSFS) for storing segments comprised of active data units, for example logical tracks, each having, when stored, an access activity value that exceeds a first predetermined threshold; and (c) storing, within the second partition, segments comprised of inactive data units each having an access activity value, when stored, that is less than the first predetermined threshold.
