On modern MLC/TLC SSDs, read-only mode doesn't really exist. The NAND blocks must be re-programmed after a number of read accesses to mitigate read disturb. If anything, mounting read-only is probably a corner case, stressing the firmware's read disturb mitigation.
The tradeoff from worse read disturb characteristics is NAND that is 100x cheaper per GB than in 2000.
- vkuruthers 8y agoDo you have any more details on the re-programming that would be occurring on non SLC flash cells, even if mounted in read only mode? This is something I was always concerned about too.
