Storage device and operating method thereof

An operating method of a storage device including a storage controller and a non-volatile memory, the operating method comprising:

• selecting a core and collecting recovery data written in a buffer memory, in response to power being cut off and a fault being detected in a performance path;
• and
• writing the recovery data to the non-volatile memory through a direct path corresponding to the selected core, wherein
• the performance path is a path for performing a write operation, a read operation, and an erase operation, and
• the direct path is a path for performing only a write operation.

An operating method of a storage device including a storage controller and a non-volatile memory, the operating method comprising:

• setting write information for writing recovery data written in a buffer memory to the non-volatile memory;
• selecting a core and collecting the recovery data, in response to power being cut off and a fault of a performance path being detected;
• and
• writing the recovery data to the non-volatile memory through a direct path corresponding to the selected core,
• wherein the performance path includes a plurality of cores, and the direct path includes one core.
