Abstract:
A disk drive is disclosed comprising a head actuated over a disk, a volatile semiconductor memory (VSM), and a command queue. A plurality of write commands received from a host are stored in the command queue, and write data for the write commands is stored in the VSM. A flush time needed to flush the write data from the VSM to the disk is computed, and the write data is flushed from the VSM to a non-volatile memory (NVM) in response to the flush time.
