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.

Do 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.
