Why do I need the red button if the green button erases data sufficiently?
The red button is impressive but whats the benefit of trashing the SSD? Or does the green button not erase data with 100% reliability?
- klodolph 14y agoIt's for organizations that have different standards. For example, the DoD has a pretty strict standard w.r.t. erasing traditional magnetic hard drives, even though `dd of=/dev/zero` should be good enough. Attacks at that point are theoretical, but they want defenses against theoretical attacks.
