All FLASH devices have an erase limit before the sector becomes non-eraseable, likely it was not a bad controller but bad choice of filesystem or bad application behaviour that was causing excessive wear in a small location.
- monocasa 7y agoWith the right access pattern we could hit it at 80kb/sec distributed writes for six hours on an SD card with a wear leveling FTL, which shouldn't be possible. We confirmed with the vendor that it was a controller bug where the FTL was losing track of a virt to physical sector mapping. Also Flash isn't an acronym and shouldn't be capitalized like that.
