After installation of a NVMe SSD in the laptop, it needs to be well-managed so that it’s life does not decrease. To do this, most modern systems use TRIM to manage and delete unwanted blocks of data on the SSD. To check if TRIM is enabled on the Linux Mint 20.1 laptop, open a terminal window and enter the following command:
sudo systemctl status fstrim.timer <enter>
It displays that old blocks will be discarded once a week in my case. This means it is working.
