Multiple Arrays for Different Disks?

[Faluzure]

I've searched the forums, but of the posts I read, it doesn't match up with what I'm curious about.

I'm finally pulling the trigger on a NAS and building myself one in the next few weeks from the post: https://forums.freenas.org/index.php?threads/hardware-recommendations-read-this-first.23069/

I plan to buy at least 2x 3TB drives for this NAS. But right now, my HTPC has various identical 1TB drives. Before you assume, no, I don't want to mix the 3TB drives with the 1TB drives in a RAID array. My question is, since I have different "sets" of identical disks, can I make an array for each set?

For example, say I use this motherboard: http://www.asrockrack.com/general/productdetail.asp?Model=C2750D4I#

It comes with 3 different SATA controllers:
Intel® C2750 : 2 x SATA3 6.0 Gb/s, 4 x SATA2 3.0 Gb/s
Marvell SE9172: 2 x SATA3 6.0 Gb/s
Marvell SE9230: 4 x SATA3 6.0 Gb/s

Assuming that the FreeNAS OS will let me, can I put the 2 3TB drives on the Intel controller, make that a single RAID array and then use the 1TB drives on the Marvell SE9230 controller and have a separate RAID array for that?

I'd really hate for my 1TB drives to go to waste, as I would have absolutely no need for them on my HTPC once I get the NAS up and running.

Any assistance is appreciated.

You can make several pools.

Under no circumstances should you use the controllers' fakeRAID or anything RAID-like that is not done by ZFS!

As long as all controllers are supported and work properly, you can connect any disk to any controller and stuff will just work.

Thanks sir. I did read about not using the controllers' RAID functionality.
