I believe a CM4 module could fit in the same space. They were probably developed in parallel, so they couldn't afford to gate the Pi 400 on the CM4 timelines.

Also, don't under estimate the performance of future SD cards.

v0, get it shipped

v1, improve

The issue with SD cards is not performance, it is longevity. I threw away more SD cards than I care to admit. :-/

What is your experience with the DVR series of SD cards?

I know there are other power down issues with SD cards and corruption well. I think in a class setting I would have important files replicated to an NFS server, with at least hourly snapshots.

I’m surprised there isn’t a market solution for long-life (SSD lifespan) SD cards. SD card is just a physical/electrical interface, couldn’t manufacturers put more resilient flash circuitry inside?

Specialized industrial use SLC microSD cards exist (e.g. https://www.avnet.com/shop/us/products/sandisk/sdsdqed-064g-...) but they cost a lot and have smaller capacities because they use SLC.
