Abstract
Old user data, old metadata, and old error correction parity information are received. New metadata corresponding to the old user data is generated. The old metadata and the new metadata are combined to obtain combined metadata. New error correction parity information is generated using the combined metadata. The old error correction parity information and new error correction parity information are combined to obtain combined error correction parity information. The old user data, new metadata, and combined error correction parity information are stored in solid state storage.
