1. A storage device comprising:
a memory including a plurality of memory blocks; and
a controller configured to:
store, according to a temperature storage level, which is used to determine when to store the temperature log information in the one or more memory blocks, temperature log information indicating a temperature of the storage device in one or more log memory blocks among the plurality of memory blocks, and
determine the temperature storage level based on a temperature change amount over time of the storage device, the temperature change amount over time corresponding to a difference between a temperature of the storage device at an end of a time period and the temperature of the storage device at a beginning of the time period.
