I hear this every year when I post new benchmark results, but it's weird, I have literally not had one microSD card failure when using any of SanDisk, Samsung, or Sony.
I had one fail with a Toshiba card, but at that time I was also using a cheap micro USB power adapter that probably wasn't putting out a solid 2A.
I think the primary reason people have problems with microSD card corruption is the power supply. Even with a good power supply, when you plug in a lot of USB devices and push a Pi to the limits, it can draw ~2+ Amps, and only very good power supplies will not have weird issues at that draw.
The Pi doesn't handle that situation very well (nor do microSD cards).
But running my Pis headless (no USB accessories attached) without any video output keeps the power draw down to 1-1.5A max, even when CPUs are maxed out and I'm saturating the network.
