I just concluded a decade long experiment. I had a USB flash drive in a jar buried in my back yard since 2015. I dug it up, plugged it in and it suffered no data loss after 11 years idle underground.

It's a usless experiment but everyone needs hobbies.

While doing environmental testing on a helicopter payload, I learned that NVMe drives (and perhaps all SSDs) can write data at high ambient temperatures >40 C, but the data is less permanent than if you write data at normal ambient temperatures.
So on hot days we had to hurry and copy our 4TB drives after the flight because the data had a half-life of a dozen hours or so.

That phenomenon is already documented, but I don't think it's widely known.

NVMe drives tend to get hot during usage - at least some models do at faster speeds. 40° C is not uncommon and by far not the highest temperature I have seen in working systems.

So what was the NVMe (not ambient) temperature that lead to this outcome? Should have been quite a lot hotter then?

Sorry I don't have the data available on the case or internal temperatures.

I agree that it was probably quite high.

Breath of relief 😉. If NVMe drives start loosing data at 40° C - that would be pretty bad!
