1. A storage device comprising:
a nonvolatile memory device comprising a memory cell array; and
a storage controller configured to:
receive event data and sensing data from an external device, and
store the sensing data in different areas of the memory cell array based on the event data,
wherein the memory cell array comprises:
a first memory area configured to store first sensing data from among the sensing data, the first sensing data being associated with a preset event; and
a second memory area configured to store second sensing data from among the sensing data, the second sensing data being associated with a current event not corresponding to the preset event,
wherein a first number of bits stored in each of first memory cells included in the first memory area is less than a second number of bits stored in each of second memory cells included in the second memory area, and
wherein the storage controller is further configured to, prior to the sensing data being stored in either of the first memory area and the second memory area of the nonvolatile memory device:
determine whether the preset event occurs based on the event data;
based on determining that the preset event occurs, determine that the sensing data corresponds to the first sensing data, and
based on determining that the current event not corresponding to the preset event occurs, determine that the sensing data corresponds to the second sensing data.
