Hello Eneko.
Disclaimer: I am replacing all EFAX (smr drives), but some of my customers don't wont to spend other money.
I know that performance is really bad, but the very big problem is that ZFS can't resilver a SMR drive, because it will be considered faultly. I am trying to make a resilver disabling write cache with hdparm, but i think that i will need a month to complete it :)
