I think it’s just hardware optimization. You get a ton more pain and risk replacing a drive in zfs vs raid10, but it’s more space efficient and flexible to use zfs. This is all academic, because the goal of these systems is a certain level of performance, availability, and data integrity, but not data safety. You need backups (preferably off-site and even off line) backups for that.
To be clear, I didn’t lose any data, ended up moving everything off the ZFS pool and went back to ext, the crashes I had just made the ZFS unavailable until I rebooted the machine.
