Abstract
A storage device is configured to utilize different encoding and decoding schemes in reading and writing data to different regions of a storage device based on the position of the storage regions and/or component-specific physical characteristics of the regions. Each encoding scheme may include multiple different types of encoders selected based an optimization process for each region.
Claims20
A method comprising:
- selecting a different encoding schemes for use in each of two or more different regions of a storage medium based on at least one component-specific physical characteristic.
A microcontroller configured to:
- select an encoding scheme responsive to a write request from a host device, the encoding scheme including:
- a first encoder selected from a plurality of encoders of a first type;
- and
- a second encoder selected from a plurality of encoders of a second type.
1 more element
A storage apparatus comprising:
- a first encoder of a first encoder type that encodes data associated with a physical block address (PBA) range of a first storage medium;
- and
- a second encoder of the first encoder type that encodes data associated with the PBA range of a second storage medium.
