In CrystalDiskInfo, I can see how many GB have been written to an SSD. This is helpful to monitor its usage over time:

If possible, I would like to run a script automatically that pulls this information and keeps a log of it over time in a csv file. I could do this easily with Python if I had some way to pull that information from the command line.

Any thoughts on how I can get the total number of host writes on an SSD programmatically? I'm not sure how to access that number from the command line.

Took them ten years, but as of 2020 CrystalDiskInfo supports command line pulling of disk information:

/Exit: Auto exit after updating S.M.A.R.T. information and AAM/APM status

/Copy: Output “Edit > Copy” result to DiskInfo.txt

/CopyExit: Output “Edit > Copy” result to DiskInfo.txt and auto exit

The last one gets you all the data as a text file. You can then pull the Total Host Writes from there with a few string manipulations, which shouldn't be difficult.
