ZFS is worth putting a little thought into your system when you START it. If you want to be able easily add a couple disks at a time, just use mirrors, I user raidz vdevs of 4 and when i need to expand i have 2 options. I add a new raidz vdev of 4 disks OR i replace all 4 disks in one vdev with

it's pretty simple, if i understand it correctly. When you add some blocks to zfs... xxx then take a snapshot (snapshot of x) the disk has the space of the x's and the snapshot does't take up any space yet then you add more to the drive and maybe take another snapshot

If you understand how copy on write works and how snapshots work then the concept of the extra space should make perfect since. If you want a mathmatic formula for how to figure it out i would have to say that it would be based on how DIFFERENT the data is between snapshots AND how MUCH data it

While it is true that you can not add a single device to a raidz vdev, you can easily add more vdevs, and this is by far the best way to grow because each vdev adds much speed to the array. Raidz is more advanced than raid5, the fact that your card doesn't do the raid calculations is not a
