Putting together the key points from your original question and your Meta question:

Are there any NVME drives above 2TB that are one-sided?

Such a product either exists, or it doesn't.

And any example of existence would answer the question.

I'm a bit torn on this one, and it might be a bit of a gray area, but I do (somewhat reluctantly) agree with closing this one.

Ok, so you clearly aren't looking for a "yes or no" answer. You're looking for an existence proof that would make it a "yes". Alternatively, such a question could theoretically be answered by a technical reason why such a thing wouldn't or doesn't exist.

But by asking for a question which you hope will be answered by a yes/example, it seems to me to absolutely be:

asking for a product, service or learning material recommendation

Note that "recommendations" aren't necessarily always (subjective) "endorsements". They can also simply be objective statements that the product meets the requirement you've placed in your question.

But the real question is why this is a problem in your particular post.

The issue, as I see it, is that any "yes" answer that provides an example would be just as valid as any other example. It may be an objective, "Yes, it meets that requirement." But it's still open-ended with no one answer being "correct", or even "most correct".

That's biggest reason why shopping recommendations are off-topic here.

Some other Stack Exchange sites share similar restrictions. Stack Overflow, for instance, prohibits requests for libraries that will meet a particular need. Certainly, the question is objective, but there may be a (very) large number of examples that correctly answer the question.

On the other hand, I've noticed that Ask Ubuntu has no such restriction, and sometimes answer will run into the double-digits because of that.

The Super User community has clearly opted for prohibiting these types of questions, though.
