Sounds about right. I would have expected the gap to be even less by 2021.
What I don't understand are the vendors who are arguing that SSD and nearline have the same or appx the same price point. For instance, IBM isn't making XIV Gen4 because, as they argue, why would they make a, primarily, nearline SAS array when they can provide SSD at the same price point. I don't see how that is possible. Same price point per I/O makes sense, but not sure how they would provide the same price point for capacity.
