And what brand are you buying?

FWIW I have several Pis running 24x7 and have not had a single SD card failure. I usually buy high end cards but I also buy cheap cards (4GB cards)and a few Micro-Center house brand, for which I don't know the quality.

I've had one that has been running years, I think. Drives a monitor, looping a video where my wife works.

The only SD card failure I have experiences was in a camera.
