Abstract: A storage device includes; a nonvolatile storage including a first region and a second region, a storage controller controlling operation of the nonvolatile storage, and a buffer memory connected to the storage controller. The storage controller stores user data received from a host device in the second region, stores metadata associated with management of the user data and generated by a file system of the host device in the first region, loads the metadata from the first region to the buffer memory in response to address information for an index node (inode) associated with the metadata, and accesses the target data in the second region using the metadata loaded to the buffer memory.
