> the company claims it has at least 4,000X more endurance than NAND and can store data for 1,000+ years.
I'm sure the company has some tests to prove those claims. /s
Anyone did a HALT test with the M-DISC ?

P.S.: we switched to the metric system.
Endurance figures come from actual testing with their 20um version. Retention is based on looking at the decay over 14h. Since it decays to begin with then plateaus they look at fitting a line to it from some time before the plateau (otherwise the answer is "infinite years") which gives 10^7 hours.

It is unclear from the article if these plots are tests of individual memory cells or a large collection of cells. Any serious attempts would involve an array of cells so a million such graphs can be plotted together etc.
