What would anybody even use 4 TB SD card for? Storing a shit-ton of pirated movies that you can watch on your phone? Aside from that I have no idea. 256 gigs is probably more than enough for anything a normal user would do on a phone.
Portable gaming Pcs. I would love to have my entire library of games accessible offline. My emulation folder alone is like 500gb. I also wouldnt call myself a normal user though. These definitely have a niche market and probably a price tag just as niche.
File size is a major limiting factor in high speed video and to a lesser extent convenient ultra HD digital film.
At 3840x2160 (basic 4k) uncompressed 10-bit video 1 frame is about 250 MB. An hour of footage at 30 fps then is about half a terabyte. At “only” 1000 fps you would burn through an 8 TB SD card in… 32 seconds.

It’s not pirating if you own a physical copy like DVD or Blu-ray, it’s fair use. Fuck the studios for trying to take that away from us.
I have a convertible laptop with a MicroSD slot. A 4TB card would be great for backups.
The target use case for large SD cards is high-resolution video recording.
Recording at 4k+ eats up space faaaaast. So you need both large-capacity as well as fast storage.

You’d need some way to cache that video, though, because it’d take 24 hours to write 8TB at SD card speeds of 80 MB/s.
Uncompressed video footage eats up storage extremely fast.
