I have 6 x 3TB WD Red disks which I've been using for some time. I just recently got hold of 2 x 3TB SAS disks and now I'm wondering what would be the best approach.
The WD disks are currently running a RAID 5 on an Adaptec controller. I've copied the data off and I'm ready to pull the controller and get it all running in my new server (with an IT flashed controller).
Up to now I've not considered mirrors, because I had too much data to fit on a mirrored setup of my current drives. The addition of the SAS disks changes that though.
Should I create 4 mirrored vdevs? This would make it easy to upgrade to larger disks, since (as I've understood) I can just upgrade 1 vdev (2 disks).
Is it better performance to create a single vdev?
