AFAIU, you are correct, but apparently, "most flash devices" does not include MicroSD cards. At least that is how I remember it.

- pjc50 7y agoNo, they've definitely got a Flash translation layer in there, and a microcontroller to run it. It's pretty much unavoidable for making a working flash device with reasonable performance on traditional filesystems.
- zzzcpan 7y agoBut SD cards, CF cards, eMMCs, USB sticks - unless enterprise graded and claim otherwise, all have either very primitive wear leveling in their FTL or none at all, it's only SSDs that have full blown log structured algorithms.
