I’m not an expert whatsoever but what I’ve been doing for my NAS is using mirrored VDEVs. Started with one and later on added a couple more drives for a second mirror.
Coincidentally one of the drives of my 1st mirror died few days ago after rebooting the host machine for updates and I replaced it today, it’s been resilvering for a while.
