I previously had a Samsung High Endurance 256Gb sd card. Despite it supported fstrim and filesystems where mounted with
discard enabled, it stopped working tonight. The write counter from Smartctl data says it has reached 3328Gb which exactly matches 13 times the capacity of the sd card.
This means unlike most flash memories which can be rewritten thousands of times, that those sd cards have only a lifespan of 13 write cycles. And with those only 13 write cycles, they are rated high endurance.
I’m putting the firmware of my rooted Android device on the sd card hence the intense write activity. That Samsung high Endurance sd card only lasted 8 months of Google Play updates.
Can you find a 256Gb micro sd card being high endurance not in name but actually in practice ?
