A method of writing data in a storage device is provided. The method includes: receiving write data from a host device; monitoring an operating temperature of the storage device; generating a plurality of write data blocks respectively corresponding to a plurality of storage regions of the storage device based on the write data; and based on the operating temperature, performing a write throttling operation including performing a write operation on P write data blocks among the plurality of write data blocks by transmitting a write command to P storage regions among the plurality of storage regions and skipping the write operation on X write data blocks among the plurality of write data blocks by skipping an operation of transmitting the write command to X storage regions among the plurality of storage regions. P and X are natural numbers.
