Media sanitization policies are a critical component of information security. As technology changes, organizations must review policy and process to ensure that it is still effective. Solid state drives require extra attention.
“Degaussing, a fundamental way to sanitize magnetic media, no longer applies in most cases for flash memory-based devices. Evolutionary changes in magnetic media will also have potential impacts on sanitization. New storage technologies, and even variations of magnetic storage, that are dramatically different from legacy magnetic media will clearly require sanitization research and require a reinvestigation of sanitization procedures to ensure efficacy.” — NIST Special Publication 800-88 Revision 1 Section 2.3
