> in cases of catastrophic failure I'm not sure it would be economical for bulk/cloud storage. It might be cheaper to just have geo-diverse redundant storage such that a failed drive can be rebuilt anew from redundant copies of the same data. I'd be interested to see if optical technologies find a niche, they seem most stable for long-term storage, e.g. M-DISK see also: https://arstechnica.com/gadgets/2019/11/microsofts-project-silica-offers-robust-thousand-year-storage/ https://arstechnica.com/gadgets/2019/11/microsofts-project-s...
