Before I opened the article I was thinking "Don't use an SD card. Don't use an SD card. Don't use an SD card."

People don't understand that 90% of the SD card problems are power related (only relevant if you don't use the official power supply) and 10% are simply because of poor SD card quality.

People haven't gotten the message that a charger has lower QC standards since an interruption of the charging process does not shut the device down. A bug that leads to a few milliseconds of power loss will pass QC, but also corrupt your SD card.

Penny drops. Yes this jives much better with the observed data -- that Rpi break SD cards orders of magnitude more than anything else that uses SD cards no matter how crappy said cards are.

Problem could have been solved by adding a decent sized capacitor on the 5v supply rail.

I think if you take into account how often they're powered on you'd find cameras destroy flash memory cards comparably to Raspberry Pis.

Or you could just buy the Raspberry Pi branded power supply.

Are SSDs less prone to corruption than SD cards when power drops for those milliseconds?
