From Wiki
Over time, storage media can become unstable and unreliable and cause data corruption or loss. A rule of thumb for a safe preservation practice is for storage media to be given only a short lifetime, sometimes estimated at only three to five years. This means that we will need to find and obtain a new storage media and migrate our data after this period. This migration is somewhat less demanding than the file format migration but still requires all data preservation actions to be performed as part of the process.
