MicroSD cards and SSD drives use exactly the same technology (NAND flash memory), so it’s a mystery to me that microSD cards are unreliable, but SSD drives are extremely reliable. Genuine SanDisk cards have failed on me for no apparent reason, but I’ve never had a problem with SSD drives with much greater usage.
- alibert 7y agoIt's the controller and the reserved/backup flash. SSD have a powerful ARM CPU running and optimizing memory cell wear and replacing these on the fly with the reserve. SD cards doesn't have that mostly for cost and size constraint.

- martin8412 7y agoI must say that I have never had an SD card fail on me. I use two in my primary camera that are setup for mirroring just in case. One in my pocket camera and one in a Raspberry PI. So maybe that's why I haven't experienced any failures. Don't know if model of card has any relevance, but I only buy the SanDisk Extreme Pro cards.
