Can 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?

The SDXC spec does not allow for cards bigger than 2TiB, because of address sizes. You need SDUC for above 4TB.

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.
