This is my experience. The only time I had an issue with corruption (using over 60 different microSD cards through 7 years and maybe 50 or so different Raspberry Pis) was when I used a little .5A microSD AC adapter that came with some cheap battery powered device that broke.

I have not had any problems when using a reliable power supply. I'm guessing the 'endurance' or 'industrial' cards some people claim are lifesavers are just doing something to guard against flaky power input when doing reads and writes, so it masks the issue.
