1. A solid state drive (SSD) comprising:
an enclosure;
a non-volatile memory (NVM) device;
a device controller coupled to the NVM device;
a capacitor;
a backup voltage line coupled to the capacitor; and
a safety assembly comprising:
a timer circuit including an input node coupled to the backup voltage line, a reset node, and an output node,
an indicator circuit coupled to the output node of the timer circuit, and
a temperature comparator circuit coupled to the reset node of the timer circuit, wherein if a temperature of the enclosure exceeds a threshold while a backup voltage is present on the backup voltage line, the temperature comparator circuit causes the timer circuit to trigger light pulses from the indicator circuit.
