alt Hacker NewsCan someone explain why in 2026 we have artificial limits like this?
> expandable upto 2TB with microSD
I get that 2TB ought to be enough for everybody, but why the heck shouldn't a 4TB microSD Just Work?

They just haven't tested anything larger.

Every time I've seen a card capacity limit like this, someone tries a bigger card and it just... works.
The SDXC spec does not allow for cards bigger than 2TiB, because of address sizes. You need SDUC for above 4TB.
