Then let me ask why are large ssds drive sizes so expensive? Let make them not expensive. There are home users that want large drive sizes.
I am not sure why this isn't a thing already. For some reason 4tb is the breaking point here when they fully have the tech to increase it.
Who made 4tb the point where shit starts getting ridiculous in $?
Because, unlike with HDDs, each extra byte of capacity in a SSD costs almost as much as the byte before it to manufacture. HDDs have most of their cost in the motors, read/write heads, housing, etc, which scale with capacity either not at all or very weakly. Capacity comes from more and higher density platters, which are a small fraction of the cost of the drive. In contrast, a SSD has most of its cost in the flash itself, with the rest of the drive being a controller and a PCB, both of which are cheap compared to the flash.
Also, as
@teubbist discussed and I briefly touched on in my earlier post, consumer demand just isn't there. Just because you're a data hoarder doesn't mean that there's a significant percentage of consumers who are, and all signs point to data hoarders being a tiny, tiny minority of consumers.
Enterprise does have high demands on capacity, but they also demand different drives from consumer drives, like SAS or EDSFF drives instead of m.2 drives, along with different performance, endurance, testing, and support requirements. This means that the big enterprise drives can cost more per capacity than consumer drives as the default condition of the market (enterprise users can easily pay a lot more because they can turn around and make more money with the better attributes of the drive, unlike consumers) and the scaling of enterprise drives don't help consumer drives scale (different form factors, architectures, and support regimes).
