A solid state disk (SSD) device, which is coupled to a host computer system, includes a non-volatile storage module (NVSM) and a volatile memory (VM). The SSD is intelligently controlled to process I/O requests received from the host, including writing data specified in a WRITE request to one or more address locations of the VM specified by the request, recording the data written to each address location of the VM as changed with respect to data stored in the NVSM for each address location, and replicating the changed data to the NVSM when not processing I/O requests from the host. |
