FWIW, only noname and Sandisk cards have given up the ghost on me. Samsung Pro & Evo cards have been doing just fine. Other than that, you just need to worry about getting proper power. Just use the official power supplies, and you're fine.
Also eMMC chips are no magic. There are crappy ones and good ones. Guess which ones you're going to get for little money?
- blackflame7000 7y agoProper power is essential. A phone charger is not a power supply even though it works. I suspect a lot of SD cards are getting undeserved blame from a PSU issue.
- geerlingguy 7y agoThis 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.
- Faark 7y agoNot having a proper power supply is my only pi related regret. Thing would freeze every once in a while. That since stopped happening, and the only change in-between (beside updates) was the initial used charger dying.
- cptskippy 7y agoI have had SanDisk, Kingston, and Sony cards die on me in a variety of devices from Pis to GoPros. Sonys were the fastest to die but retained read capability, where as the SanDisk just stopped functioning completely. My most recent additions are a Samsung Evo card and a Samsung Endurance. I am curious to see which dies first.
