That's also the reason why boards that depend on SD card rather than for example eMMC are despised in the industrial world. SD cards are highly unreliable, whatever their brand or price: it's just a matter of when they will fail; I've lost count of how many of them I had to pull out and check/recover on my formerly Raspberry PI based media center before I ditched it for a Chromebox with reflashed firmware. Now that's not a big hassle in a home media center, but I wouldn't want for example to travel 300 Km to a mountain and climb a 20 meter pole to service a sensor up there that stopped working because its SBC SD card failed.
