Twinstrata released a comprehensive report describing a 3-yr TCO for

storage as a service offerings. Detailed economic data supporting each
medium along with breakpoints (in TB) on when it makes the most
economic sense to use a specific platform or service is provided in a
presentation format. No registration required to download the report.
