As I shared in another post, compared to my linux machine, most of the posts, including yours, have atleast 5x-10x the usage. I understand that disk usage can vary wildly, but the linux machine I'm comparing with has been used through the work week for the past 6 years with VMs/docker and other large files.

On the other hand my linux Thinkpad has worryingly high numbers:

    Available Spare:                    100% 
    Available Spare Threshold:          10%
    Percentage Used:                    6%
    Data Units Read:                    123,210,825 [63.0 TB]

Power On Hours seem to indicate the disk has been on for a good chunk of time, so I would think you're doing fine. Percentage used says 6%, so that seems decent too.

What model SSD is this?

Honestly I’ll probably replace this computer much before this becomes an issue.
