Abstract
Systems and methods are disclosed for employing variable amounts of parity sectors. In certain embodiments, an apparatus may comprise a processor configured to generate a first number of parity sectors for write data to be written to a nonvolatile memory, and store the write data and a second number of parity sectors to the nonvolatile memory, the second number of parity sectors being a subset less than all of the first number of parity sectors. The processor may further select additional parity sectors from the first number of parity sectors based on error metrics for the write data, store the additional parity sectors to the nonvolatile memory, and perform error recovery on the write data based on the additional parity sectors.
