The curious case of the Raspberry Pi in the network closet (2019)

Compute module has eMMC, and they haven’t been excessively costly because of it or reportedly unreliable in the way SDs are. But either way I suspect that the Foundation design team has some issues in designing power circuits rather than that SD cards being unfit or people are throwing in cheap ones.

Well, that was the issue with older Pis is that they were running powered by (micro) USB 2.0, which officially tops out at 2.5 W. While IIRC the 3rd Pi tended to top out at trying to draw 15 W - SIX TIMES MORE !!! No wonder that SD cards got destroyed in the process !

But AFAIK this shouldn't be an issue any more (assuming a non-counterfeit charger) with USB-C 3.0 (RPi 4+ ?) which starts at 15 W ?

I don’t know, but they did have brownout issues with 5.0V supplies, reluctance issues or something with official PoE HAT, and I’m not seeing PC-like multi phase MOSFET bridges on Pi to this day. It could be like there is some spike noises or something going into SD and killing it(emphasis on could be, it’s just my hunches).
