Abstract
Provided are a method and apparatus for an error tolerance aware data retention scheme in a storage device for multi-scale error tolerant data. A mapping of retention priorities to sectors of the storage units maps higher retention priorities to sectors having a higher retention capability. A data stream and retention metadata for the data stream indicate retention priorities for segments of the data stream. Segments of the data stream having less error tolerance are mapped to higher retention priorities than segments of the data stream having greater error tolerance. The mapping of retention priorities is used to determine a sector having a retention priority matching a retention priority of a segment of the data stream indicated in the retention metadata. The segment of the data stream is stored in the determined sector.
