Northern Star states in its website that by having integrated this this metal based composite into the optical media, DTD is a unique permanent storage and archiving solution; which has showed to have a data life expectancy of 160 years in its accelerated age test in simulations of extreme environmental conditions; thus no environmental impacts such as heat, humidity or light have shown to have influence on the longevity of DTD.

According to Northern Star DTD is:
• Backwards compatible with all common burners and readers including Blu-ray writers. Therefore no fear in the future of technology obsolence.
• Not only safely storing data, but as well archiving without the need to rotate or migrate data every two years. No special storage requirements.
• Once data burned onto „DATA TRESOR DISC”, no alteration or overwriting possible, therefore safe from manipulation.
• Low cost archiving solution with reduced storage costs.
