To be objective you should have mentioned that US Department of Defence did a similar test and they did end up claiming that M-discs lasted for longer than regular discs. It looks like someone took over the production of M-Disc (wiki: "The debt holders subsequently started a new company, Yours.co, to sell M-DISCs and related services."), not sure about Syylex. Syylex seems like the perfect solution (making discs in glass, the material that is routinely used in chemical labs due to it's inertness), but the problem always was that it cannot be burned at home...
