Abstract
This disclosure describes a non-volatile storage device includes a non-volatile storage and a controller. The controller includes a data evaluator to evaluate each block of data stored in the non-volatile storage, the evaluation being made in accordance with multiple integrity factors; a factor evaluator to provide a weight to each of the multiple integrity factors for each of the multiple blocks of data, aggregate the multiple weighted integrity factors for each of the multiple blocks of data, and identify one of the multiple blocks of data stored in the non-volatile storage for which the aggregated weight integrity factors is highest; and a scanner to perform at least one media scan of the identified block of data stored in the non-volatile storage, e.g., NAND flash memory.
