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
- Drdrdrq 6y agoThe issue with SD cards is not performance, it is longevity. I threw away more SD cards than I care to admit. :-/
- seg_lol 6y agoWhat is your experience with the DVR series of SD cards? https://carcamcentral.com/guide/recommended-microsd-cards-for-dash-cameras https://carcamcentral.com/guide/recommended-microsd-cards-fo... 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.
- throwaheyy 6y agoI’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?
- ThrowawayR2 6y agoSpecialized industrial use SLC microSD cards exist (e.g. https://www.avnet.com/shop/us/products/sandisk/sdsdqed-064g-xi-3074457345639505458 https://www.avnet.com/shop/us/products/sandisk/sdsdqed-064g-...) but they cost a lot and have smaller capacities because they use SLC.
