Not all use-cases require a high speed:capacity ratio.

I mean, I have an 18TB USB hard drive, which sustains transfer at about 50MB/sec in practice. It is nearly full, and its level of performance has never been a show-stopping problem.

It's hard to imagine a use case where a NAS would be a viable alternative to an SD card.

I've had a usage tier for storage that looks like this

Temporary storage

SD cards - unreliable storage you use temporarily to store pictures and videos before inevitably moving them to a more reliable and permanent solution.
USB drives (hdd ssd etc) - used for when you you want to move files faster or more conveniently than over a Lan.

Permanent storage

Nas, internal drives, tape drives, etc - for when you want to store a lot of data with configurations that allow you to use redundancy.

The issue with super high capacity SD cards for me is that they're still fragile and prone to failure. When you allow someone to store that much data, it'll be used as a more permanent medium, and since it has a lot of storage capacity you end up with a bigger data loss when it dies. Imo having 30 128gb SD cards would be better because if one dies or breaks, you lose 128gb and not 4tb.

Tldr I think 4tb micro sd cards are stupid.
