If you have an SSD they’re life span is measured in trillions of writes. Your SMART utility already measures SSD life but not for NVMe SSDs. For that you need nvme-cli. To install it use:
sudo apt install nvme-cli
Next gather information available from SSD:
$ sudo nvme smart-log /dev/nvme0

The most important field is Percentage used which shows as 0%. This isn’t disk usage percent but life used percent. I’ve had this drive since October 2017 and now it’s December 2018. As soon as Percentage used hits 1% I can multiply the number of months I’ve owned it by 100 to find out when it will die. At the current rate I can say the drive will live 100+ years. Of course it will be obsolete in ten years anyway.
Notice the temperature report.
