摘要： 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.

摘要： A method of recovering data in a storage device is provided. The method includes: receiving backup storage information associated with a backup storage device from a host device, both the host device and the backup storage device being external to the storage device, and the backup storage device being configured to store backup data corresponding to first data; performing a data read operation on the first data; based on an unrecoverable data failure occurring while reading the first data, directly receiving the backup data corresponding to the first data from the backup storage device based on the backup storage information; and performing a data recovery operation for the first data based on the backup data.
