Maybe because your statement about SSDs is incorrect. Consumer SSDs have spare blocks too, and wear leveling prevents the scenario you're describing.

I appreciate the reply, but my warning consumer SSD is not incorrect. Perhaps I should have clarified that While they typically have a small overprovisioning of 7%, enterprise SSDs have close to 4 times as much, exactly to allow more writes (which is very relevant if running a ZFS raid on the drive). Keeping 10-20% headroom will prolong your SSD's life significantly, and increase performance of ZFS.
Go ahead and let them try consumer SSD's. It seems to be a lesson everyone has to learn with ZFS once.
