I'm with Vince. I believe the micro-SD cards are perfectly reliable. As an experiment I've been running WeeWX on an RPi B+ with an SD card for over 9 years. The key is a reliable power supply connected to a UPS. Webpage: https://www.threefools.org/weewx/status/index.html
I'm getting tired of waiting for it to break --- it's taking up too much space on my desk. If it doesn't break soon, I'll probably end the experiment.
