Quite possibly! Flash memory is absolutely not all the same. I wish someone would do for SD cards what Backblaze does for hard drives.

Oddly enough, Samsung, SanDisk, and Sony are the three brands I've had die on me. I had a GoPro eat two Sony cards in less than a year, I switched to SanDisk Endurance and it's been plugging along for about 2 years now. I've had one Samsung and a couple SanDisk SD cards die in Raspberry Pi's. I'm currently using MicroCenter, AData and one other lower tier brand that have held up much better than the name brands.

Those will still eventually die due to log being written to the card using all available read/write cycles.

You mean /var/log or filesystem log? What about using non-journaling filesystems or keeping /var/log on a ramdisk?

That's a problem that will eventually affect any flash solution -- SD card, SSD, or USB flash.

They usually just stop accepting writes (silently). It's a bit of a head scratcher at first. But at least it doesn't lead to a complete data loss.
