My question was closed as off topic.
The only feedback was the boilerplate:
Closed. This question is off-topic. It is not currently accepting answers.
Questions seeking product, service, or learning material recommendations are off-topic because they become outdated quickly and attract opinion-based answers. Instead, describe your situation and the specific problem you're trying to solve. Share your research. Here are a few suggestions on how to properly ask this type of question.
I addressed pointed out issues in a comment, but there was no reply. After I few edits of the question I flagged for moderator attention, but it was refused, again with no feedback.
The boilerplate links to What topics can I ask about here? where it says:
If you have a question about … computer hardware … then you’re in the right place to ask your question!
My question is about hard drives, which is computer hardware.
The boilerplate also says:
Questions seeking product, service, or learning material recommendations are off-topic
My question is not seeking any recommendations.
The following text is about recommendations, if I understand correctly, so unrelated to my question, but I will (and already did in the comments of my question) address them:
"become outdated quickly"
My question is about a property of hard drives, that is as old as they (so roughly 30 years) and will be relevant as long as HDD (and similar devices) will exists, and currently there is no end of HDD use in sight.
"attract opinion-based answers"
In my question is about clarification of a certain claim and specifically emphasizes that it seeks evidence, not opinions.
So, please help, as I don't see why the question is off topic on this site.
PS: The second link in the boilerplate links to a question about "recommending software", so not really related the rest of the text (well, it is but only partially).
PPS: Meanwhile the question was (auto)deleted.
PPPS: I edited the question, removed the disputed part(s).
