Interesting John. What ThinkPad do you have? I have had a couple of the 128gb SSDs in our T410s fail, some after less than a year. I have been replacing them with Samsung or Kingston SSDs. I have not had problems with either. The original were Intel, which I would think would be decent, but I guess not. Other then the drive issues the T410s have been great machines. They each are used by different people for various purposes and run a smattering of OSs (Win7, Win10, Debian, Ubuntu), all still going strong. I have a second SSD in the bay of my T410 with Debian 9, I have Win7 on the original (yet to fail) SSD (it may never fail since Win does not get much use!).
I also have one each of the T41, T42, T43. The 43 runs Debian 8 and I use it daily. Other two are a little tired.
