Wait, are we sure it's not just FTL at play?

Totally agree, wear-leveling makes sense here.

I thought it was NAND degradation, but I guess not!

This is definitely an example of wear-leveling.

I’m torn between wear-leveling and NAND degradation. I remember discussing how data can appear multiple times, but I can't recall which one it was specifically.

This question feels familiar; I think we had a practice question about LBA and FTL. I might lean towards FTL, but I could be mixing them up.

I remember something about wear-leveling, but I'm not confident if that's the right answer here. It could also be NAND degradation, right?

I think this might be related to the Flash Translation Layer, but I'm not entirely sure. It seems like something we covered in class.

Ah, I've seen this kind of issue before. My money's on the Intelligent Wait stages not being used properly. That's a common pitfall when moving from development to production.

I'm pretty confident this is true. The question mentions the customizations remain in effect even if you leave and return to the view.

Hmm, I'm a bit unsure about this one. The options seem to cover different places where the output could be located, but I'm not sure which one is correct. I'll have to think this through carefully.
