You understand you just insulted my entire race of people?

But yes.

In my experience, using spinning disks, the performance is very poor, and times for scrub and resilver are very long. For example, in a raidz1 with 4x8TB, scrubbing takes 2-3 weeks and resilvering takes almost 2 months. I must also add very poor performance in degraded state. This is a very old post, but things are still the same.

If op is considering ZFS: Do. Not. Use. RAIDz. (learned the hard way)

Why three, if don’t mind if I ask

I know
