Abstract
A data storage device can store data and parity information for the data in its memory. In some storage methodologies, data and parity information are striped across a plurality of memory dies (e.g., in a redundant array of independent drives (RAID) configuration). That way, if one of the memory dies fails, the data or the parity information can be reconstructed from the other memory dies. These embodiments recognize that because parity information is used relatively infrequently, the parity information can be stored in locations in the memory that have a relatively-worse performance than other areas of the memory. This can increase performance of the memory in situations where the parity information does not need to be read.
