My mmc heavily degenerates as well:
My emmc is from Nov 2019. The dump2fs Life Time writes start Dec 2019, e.g. don't log the usage of the first month. That is negligible.
(*) dumpe2fs /dev/dm-0 2> /dev/null | egrep "Lifetime"
Over writing 85GB (50% of these 85GB are for updating Debian 12 to Debian 13), the life time degenerated by 20%. Over writing further 2 GB, the life time degenerated further 10%. This degeneration is not proportional and I expect this emmc to die in the next few days or weeks.
Writing 1000GB is like writing the whole 128GB emmc less than 8 times. That is a very low number. The data-sheet https://files.pine64.org/doc/datasheet/p...0v1.13.pdf suggests that the expected life time is writing 88,0000 GB for my 128GB emmc module (given a certain workload mix).
A questions to others. What the health of your emmcs: Run this command:
