You aren't concerned about cosmic rays? https://en.wikipedia.org/wiki/Cosmic_ray#Effect_on_electronics https://en.wikipedia.org/wiki/Cosmic_ray#Effect_on_electroni... >> Studies by IBM in the 1990s suggest that computers typically experience about one cosmic-ray-induced error per 256 megabytes of RAM per month.[76] To alleviate this problem, the Intel Corporation has proposed a cosmic ray detector that could be integrated into future high-density microprocessors, allowing the processor to repeat the last command following a cosmic-ray event.[77]
