Hi Mark, > I am wondering what the impact of in-place writes of the > superblock has on SSDs in terms of wear? Typically SSDs have far more advanved static wear leveling algorithms which keep the erease count for each erease block as well as a sophisticated mapping table. Otherwise e.g. journaling file systems would probably kill it quickly.
