Abstract
A hybrid storage device that includes a hard-disk drive (HDD) and a flash memory is described. When control logic in the hybrid storage device receives a request from an external device to write a block of data to a logical address in a first portion of an address space that maps to the HDD, the control logic writes the block of data to the HDD. However, if there is a change in environmental state information of the hybrid storage device during the write operation, the control logic writes at least a portion of the block of data to a logical address for the block of data in a second portion of the address space which maps to the flash memory. Note that the address space may be common to the external device and the hybrid storage device.
