To what? Some context would be helpful.
I mean, if I have to resilver a raid with 3TB discs, it can take days I suspect. With 4TB disks it can take a week, maybe. So, if I use mirror and one disk break, then I only have single redundancy while the mirror repairs. Reparation will take long time and will stress the disks, which means the other disk might malfunction. Therefore, I think raidz2 or raidz3 that allows 2 or 3 disks to break while you resilver. Hence, mirror is not a realistic alternative when using large disks. True/false? What do you guys say?
I don't have any exact like for like comparison data, but from what I've seen a mirror resilvers a lot faster than a drive in a raidz(2) vdev.
