The US Department of Defense has an often-quoted specification for data shredding on magnetic disk media.

Optical storage remains a top choice for compliance

Storage technologies, such as WORM on magnetic disk, enable the "locking down" of data, enabling corporations to prove it has not been tampered with or deleted, but with the responsiveness and reliability of magnetic disk and its associated RAID protection.
