Hi there,

I'm not an expert in ZFS (I know enough to be a dangerous fanboy, haha), but I have an unraid server with two ZFS pools: one with HDDs and one with SSDs.

I recently bought a new 4TB Samsung 990 Pro SSD and want to add it to the SSD pool.

My initial thought was to add the 990 to the pool as a new VDEV. However, I'm also considering recreating the SSD pool with two drives in a strip configuration. I don't mind disk failures because I regularly snapshot and back up the SSD pool to the HDD pool.

The main goal is to have access to all 5TB of storage.

I'm wondering if it's a good idea to combine these drives into one pool or if it would be better to create three separate pools.
