Abstract
A storage device may store performance information of the storage device in a target memory area including one or more of a plurality of memory blocks on determination that a set target condition is satisfied. And the storage device may control a target operation based on the stored performance information.
Claims18
A storage device comprising:
- a memory including a plurality of memory blocks;
- and
- a controller configured to:
- store performance information of the storage device in a target memory area including one or more of the plurality of memory blocks on determination that a target condition is satisfied;
- and
- control a target operation based on the stored performance information,
- wherein the performance information includes a size A of data written, during a reference time period, in a first memory area including one or more first type memory blocks from among the plurality of memory blocks, and a size B of data written, due to a failure to write to the first memory area during the reference time period, in a second memory area including one or more second type memory blocks from among the plurality of memory blocks, and
- wherein the first type memory blocks operate at a higher speed than the second type memory blocks.
