ABSTRACT:
A dual disk drive peripheral data storage system is disclosed. The dual disk drive is a combination of a hard disk drive and a solid state disk drive whereby the solid state buffer memory that is typically used as a data cache for the hard disk drive is partitioned such that one portion provides the memory for the solid state disk drive while another portion remains as the cache for the hard disk. The dual disk drive provides the capability for a user to repartition the solid state buffer memory such that the sizes of the solid state disk drive memory and cache memory can be adjusted to increase the data transfer rate with a host computational system.
