As long as you aren't relying on it as backup, it doesn't matter for most use cases. I'm about to build a zpool consisting of nothing but 3-wide raidz1 vdevs.

As long as you aren't relying on it as backup, it doesn't matter for most use cases. I'm about to build a zpool consisting of nothing but 3-wide raidz1 vdevs. I can tolerate one drive dying. In the ~8 years or so I've been running a NAS, I've had precisely one drive failure. I am fully aware that survivorship bias is a thing, and anecdotes aren't data, but it's good enough for me. Anything important is backed up locally and to the cloud. Everything else is merely annoying to have to download again.
