How to see TBs written for a specific drive?

[VitoBotta]

Activity Monitory shows data written across disks so it includes TimeMachine backups etc. How can I monitor how much data is written to a specific SSD?

Looks like DrivDx shows this information.

Look at GrandSpective sense it is Universal!

I think this app only shows the space taken, right? I was referring to data written in total over time, to evaluate the life left in an SSD.

I use smartmontools via Homebrew in Terminal. My startup SSD:

ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE
241 Total_LBAs_Written      0x0032   099   099   000    Old_age   Always       -       90727806382

FYI: Smartmontools don't work fully with external USB drives since macOS doesn't support SCSI pass-through. There is a third party driver, which gives some functionality, at least for older macOS. But it all depends on the chip present in the USB drive.

I got it with DriveDx but will take a look at smartmontools, thanks
