I log to tmpfs, use sane filesystem that was designed for flash storage (ie tries to reduce write amplification effects), and most of my uSD cards already clock >5years with frequently updated arch linux arm running on them the whole time + services they are meant for.
Looking at stats, my SBCs take between 9-30 GiB of writes a month. So that's already 1-2TiBs of total writes. That doesn't sound like much. Like 30-60 total overwrites of the SD card. I'd expect the card to take 200-500 complete overwrites.
Basically infinite lifetime with this amount of write load. PSU will probably stop working before the SD cards will.
