The only possible explanations I have for the difference in your results and mine with Etrecheck, and confirmed by Disk Utility, TechTool Pro, Tinkertool System, and Drive Genius are:
- I am using a different version of MacOS (10.13.2 beta 4)
- My SSD is formatted APFS (but S.M.A.R.T. is purely hardware and the format should not effect the hardware)
- I have a different model MacBook Pro
- I am not holding my mouth right when I run Etrecheck or any of the other utilities
Smart Alec apparently has a much lower "verified" tolerance and I concur in its estimate.
How did you determine that if Smart Alec couldn't see your SSD?
I base that on
- a previous version of Smart Alec that I beta tested on my Mac mini
- Assumed from comments made by Smart Alec developers (I know — assumed)
- Knowledge of S.M.A.R.T. test limitations reported many years ago by Google Labs
- Years of experience seeing all the various parameters via TechTool Pro
- Two occassions of drives reporting "verified" in Disk Utility while TechTool Pro was showing multiple failed S.M.A.R.T. parameters when the drive had actually failed
