SD expires cards are still on my watch list after seeing this https://www.theverge.com/2021/9/9/22665216/sd-express-card-s.... But even then, that's only 3x faster, so you're still putting down 71 ish (I think my original number was 213.33) cards, which means 71 PCIe PHYs and NVMe stacks.
Get a PCIe 4 model and then you're at 35, and that's microSD doing that speed so 35 microSD is pretty compact.
For a thought experiment that's not even optimized for speed, that's pretty good.
