I have a newly built server that I am testing FreeNAS 10 (Corral) with. I currently have a zpool with one 6 drive vdev in Raidz2. These are WD Red 6TB drives. I am looking at expanding the pool with a second or third 6 drive vdev. I have an existing server I could steal 3TB drives from to setup a second vdev, but this won't be sufficient in terms of capacity and I would need to add a third in short order, likely WD Red 4TB based on the pricing. Result would be 18 drive pool in 3x6 drive vdevs.
Alternatively I have been considering biting the bullet on 6 new 6TB / 8TB drives and just added a second vdev. Setting aside the risk of more drives = more failure points, is there any performance differential between the two? Should I limit the number of drives or vdevs in a pool?
Thank you.
