is that because the drive is compressing the information? is there a way to turn this off? i hate mandatory compression as losing one bit in a compressed file tends to be a big deal compared to the same in an uncompressed file. -- Securely sent with Tutanota.

SSD's, in particular SD Cards (which you're not using, which is noted as /dev/mmcblk0...) store you data as a probabilistic representation, and through a lot of magic, the probability of retrieving your data correctly from SSD is made very high. Almost deterministic.
The magic is in the firmware, and so there's some possibility any given SSD problem is related to a firmware bug. So it's worth comparing the firmware reported by smartctl and what the manufacturer has, and then their changelog. Most have a way to update firmware without Windows, but don't have images that will boot an arm board, usually the "universal" updater is based on FreeDOS funny enough. You'd need to stick the SSD in an x86 computer to do this. Hilariously perverse, I did this with a Samsung 830 SSD a while back, sticking it into a Macbook Pro, and burned that firmware ISO onto a DVD-RW, and it booted that Mac (using the firmware's BIOS compatibility support module) and updated the SSD's firmware without a problem.
