Ars spoke Tuesday with Dr. Ant Rowstron, a principal researcher at Microsoft Research in Cambridge, UK, about an innovative cold storage project called Silica. Silica aims to replace both tape and optical as the media of choice for large-scale, (very) long duration cold storage. Microsoft Research is partnering with film giant Warner Bros., which is directly interested in reducing costs and increasing reliability in its own cold storage programs.

I find the topic highly interesting. It’s also directly relevant to cryonics, as the digital data about the patient’s mind could play the key role in the future reanimation.
As far as I know, there are currently 4 types of highly durable data storage available to end-users:
Linear Tape-Open:
Claimed longevity: 30 years, Cost per TB: ~$50. Minimal price to buy the hardware etc: ~$300.
M-DISC:
1000 years. ~$130 / TB, Min: ~$100
Nanofiche:
>1000 years, ~$10 000 / TB (?), min: $50 000.
Paper books on demand:
>1000 years under some conditions, > ~$1 000 000 / TB, min: $50
I know a German cryonicist who is also experimenting with granite as a data storage medium. A massive slab of granite could easily outlive all of the aforementioned types of media. But, to achieve a reasonable storage capacity, one need to find a way to utilize the entire volume of the stone, not only its surface.
