Abstract
A data storage device is provided. The data storage device may include a buffer memory, a storage medium, and a controller. The buffer memory may be configured to sequentially store written data blocks received from a host. The storage medium may be configured to include at least one drive. The controller may be configured to calculate first parity data for data selected from the written data in the buffer memory, generate journaling data, and control the generated journaling data to be stored in the storage medium. The data storage device may decrease a number of inputs/outputs used for a parity calculation to thereby reduce overhead.
Claims15
A data storage device, comprising:
- a buffer memory configured to sequentially store written data blocks that are received from a host;
- a storage medium comprising at least one drive;
- and
- a controller configured to:
- calculate first parity data for selected data that are selected from the written data in the buffer memory;
- generate journaling data comprising the selected data and the first parity data;
- and
- control the generated journaling data to be stored in the storage medium.
A data storage method, comprising:
- sequentially storing, in a buffer memory, written data blocks that are received from a host;
- calculating, by a controller, first parity data for selected data that are selected from the written data in the buffer memory,
- generating, by the controller, journaling data comprising the selected data and the first parity data, and
- controlling, by the controller, the generated journaling data to be stored in a storage medium comprising at least one drive.
