I hope this becomes a sticky and some of the more advanced users would contribute.
I was hoping to start/create a thread about ZFS scenarios - I could not find a similar post.
When it comes to ZFS one would definitely feel more safe creating resilient arrays with RaidZ2 config than multiple mirror VDEVs in the same pool.
Suppose one has 5 disks, mixing a mirror and a 3 disk RaidZ1 in the same pool would be like mixing tuna and chicken in the same ceasar salad. A no-no.
Some newbie configs still might include this.
SCENARIO 1:
3x 1.5 Tb disks - I would use a RaidZ1 - most likely with a cloud backup for really important suff. One disk
SCENARIO 2:
6x 2 Tb disks - RaidZ2 would make more sense than 2 3 disk raidZ1 VDEVs as you could fail any 2 disks with the former while only 1 of each group of 3 in the latter.
SCENARIO 3:
2x 2Tb disks - Mirror might give resiliency, but if drives are larger than 2 Tb it could be that investing in a 3rd disk of the same capacity is better? I am not an expert here.
Other scenario recommendations are welcome.
