Hmm, 33.5GB per day cannot be possible.
The whole /var has only ~18GB which would mean writing the complete /var approx. twice per day, which surely does not happen.

However... you can not write, say, 100 bytes on flash media, you have to write the entire 32KiB block. That is, read it, modify the 100 bytes you need (in memory) and then write again the 32 KiB block. That makes for a much larger figure.

/boot is not a problem imho.
So either is wrong or smartctl.
Or both.

Or our interpretation.

The firmware of the disk says "34" out of 100. It doesn't matter what it means exactly, but for practical purposes, replace the disk ASAP when it gets to 99, and have the replacement ready at 95 or earlier.
