Abstract
Apparatus and method for managing data in a hybrid data storage device. In some embodiments, the hybrid data storage device has a hard disc drive (HDD) controller circuit coupled to non-volatile rotatable storage media and a solid state drive (SSD) controller circuit coupled to non-volatile solid state memory. A local memory stores a map structure which identifies logical addresses of current version data sets stored in the solid state memory. A top level controller circuit operates responsive to the map structure to direct a selected host data transfer access command to the HDD or SSD controller circuit. The map structure may be arranged as a plurality of discrete logical address sequences, where a gap is provided between each adjacent pair of the discrete logical address sequences in the map structure.
