I strongly disagree with this old blogpost. I feel that this advice is a somewhat dishonest attempt to plaster over the fact that you can't expand a VDEV. https://louwrentius.com/the-hidden-cost-of-using-zfs-for-your-home-nas.html https://louwrentius.com/the-hidden-cost-of-using-zfs-for-you... So you try to burry that fact by promoting mirrors. But mirrors aren't as safe as RAIDZ2 and they aren't as space/efficient. It all depends on circumstances, but if you want to store a ton of data, RAIDZ(2|3) seems the right way to go. Use RAIDZ(2|3) vdevs, not mirrors.
