FWIW I have not had any SD corruption issues after 1) using name-branded cards and 2) ensuring that I feed each Pi w/5.2V. In the end I bought a commercial 5V power supply, tweaked it up 5% and wired directly to the 5V pins on the Pi.
- magicalhippo 6y agoI'm running several Pi's from SD card, some for years, and the only issue I had was with one that randomly crashed. Measured the resistance of the "USB charging cable" I had used for it and found it was 1 Ohm! So when the Pi peaked at 1A current draw, the cable dropped 1V. Swapped it out for something proper (<0.1 Ohm), and haven't had issues since.
- mmastrac 6y agoSame here. I even went as far as finding barrel-jack to USB connectors so I could wire thicker-gauge cables to the Pi. In the end I gave up on trying to find low-ohm cables and just wired directly to the power supply. It's surprising how many cables just plain suck.
