The problem is prices of ultra high capacity SSDs have not really come down with time, and have actually increased in most cases from the under $100/TB to double digit percentages higher, with gold standard 2TB drives like the WD SN850 and Samsung 980 Pro sitting at $120/TB. 4TB and higher SSDs haven't seen the same kind of drop towards affordability.
Yes the need for higher than 2TB SSDs in the consumer space is rather limited given how easy it is to offload games and such to hard drives, as well as using 2-2TB NVMe drives in spanning RAID, but still by 2022 you would think 4TB and higher NVMe SSDs would be far more affordable than they are.
