In an example, a method, non-transitory machine-readable storage medium, and apparatus is described for preserving data in a solid state drive in the event of an unclean shutdown of the host computing system. A controller of the host computing system detects an unclean shutdown that initiates a power down of the host computing system, In response to the detecting the controller asserts a first signal that signals the solid state drive to write data in a volatile memory of the solid state drive to a non-volatile memory of the solid state drive, The controller then initiates a timer to count down a predefined delay period after the asserting. Upon an expiration of the timer, the controller asserts a second signal that instructs a power supply of the host computing system to power off.
