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.
