You can also use SmartMonTools in HomeBrew to show these numbers via Terminal. I know there’s been plenty of pages of comments, but it’s been covered a few times now.
Thanks for the tip. I've purchased and installed. My M1 MacMini's SSD seems to be in the green. This MacMini was purchased within the first month of release.
Does DriveDx work with Monterey?
I've used SMARTReporter with this same mini in Mojave with Binaryfruit's signed satsmart-kext.
In theory it should but while it will run on Catalina on my Intel iMac it won't give me any information but on the Internal platter:
I see few reasons:
The guts of DriveDX, smartmontools, is open source and free. Someone took that and rewrote it using Apple's own SMART APIs so unless they did something really silly, Apple's API are wonked, or the drive in question doesn't support SMART through the connector smartmontools should work (It may not like USB because I can't get it to give my any information on any drive connected on my 2013 iMac via USB)
I think what's great about smartmontools is that you only need to type 'smartctl -a disk0' in a terminal window. No need to install DriveDX at all.
To get SMART from externals, you need SATSMART kext.
There are doubts about smartmontools working right with macs.

Did you cross check these numbers with Activity Monitor (Disk Tab)?
You DO know, that Activity Monitor (Disk Tab) shows you numbers only from last boot?

I have an intel mac mini (2018).
My internal ssd is small and quite full. Hence the reason to use externals to boot.
That could be a cause. I have found Apple's Catalina OS to be a temperamental little OS beginning with Catalina Security Update 2020-001. To boot off the external SSD on my 2013 iMac I have to unhook all other drives and I am not the only one to have this issue. And for some gonzo reason the machine will just cut out (I suspect kernel panic but I really don't want to deal with my insanely slow internal platter drive).Like I wrote: I don't use the internal ssd at all.

BUT now that I think about the history, there was big problems to migrate data in 2019 from my old mini2012. I had idea to put system to the internal ssd and home folders to external and Mail migration did not work and Apple's support told me to repair permissions, which ran for days and still didn't work.
Maybe those times in 2019 the internal ssd had several terabytes of writes...
Home Folder in external disk "not supported" by Apple
Here's the problem: Home Folder in ext disk "not supported" by Apple diskutil resetUserPermissions / `id -u` Long story short: I tried to avoid apple tax by buing mini with small int ssd. Seems to be that at least for 10.14., You have to have your home folder in startup drive, otherwise you...
As I mentioned having a near full SDD can cause write issues. While I got a 1TB external SSD I keep it as empty as sanely possible with all documents on an external platter drive:
