this is impressive, seems that SDUC is just a specification so it applies to both full-size and micro SD cards. I don't know of many devices that still support full-size but I hope to one day see a 128TB microSD card. Not sure how they'll figure it out, last I check the biggest size Sandisk sells is 2TB tho the article mentions we'll be seeing 4TB+ cards soon.
What worries me, given my time with the raspberry pi, is reliability. They seem prone to random failure, not that I've personally ever had a card die on me (and it seems that even in failure they lock into read only mode so you don't lose data?), but it seems that there's no standard way to check the health of the card like you can with SSDs using SMART data. This makes me hesitant to trust larger-capacity SD cards for data tho I know of some industrial cards that seem to have some kind of support for viewing card health but I feel safer with small capacities since there's less to lose if something goes wrong but faster speeds are always a plus.
