Uses

To optimize storage costs, cold data can be stored on lower performing and less expensive storage media.cite-ref-2[2] For example, solid state disks may be used for storing hot data, while cold data can be moved to hard drives, optical discs, tapes, or migrated to cloud storage.cite-ref-3[3]cite-ref-4[4]
