Claims20
A method of managing data of a storage system, comprising:
- storing write data transferred from a host in a storage device;
- and
- performing a scrubbing operation for verifying validity of the stored write data by the storage device in response to a scrubbing command from the host, the scrubbing command comprising a validity verification period of the scrubbing operation.
A storage system comprising:
- a host configured to provide write data and a scrubbing command on the write data;
- and
- a storage device comprising a nonvolatile memory to store the write data, the storage device being configured to verify validity of the stored write data in response to the scrubbing command and to provide a validity determination result, indicating the validity of the stored write data, to the host.
A storage device, comprising:
- an interface configured to interface with a host;
- a controller configured to receive write data and a scrubbing command from the host via the interface, and
- a memory device configured to store the write data,
- wherein the controller is further configured to verify validity of the stored write data in response to the scrubbing command, the scrubbing command comprising at least one of a validity verification period and a validity verification range, and to provide a validity determination result, indicating the validity of the stored write data, to the host via the interface.
