Any reason to leave performance on the table by not configuring all of what you bought in a reasonable manner?
Simple: Committing all disks to aggregates when you don't need to
squeeze out every last bit of performance locks disks to specific nodes unnecessarily. Then, when you need more disks on a particular node, rather than just moving over disks from an underutilized node, you have to buy new disks or even a new shelf.
