The inflation losses are much more noticeable on raidzN than on mirrors for example (e.g. for each miniature file, tail or metadata block that used 512b*3 on a raidz2, you now use 8k*3 for example). There is also padding overhead on raidzN for incomplete-stripe files or tails, to ensure that whenever you delete something, you can stick a trivial block of at least N+1 sectors in the newly made hole.

I am on mirrors.
