RAID 0 config - install in SATA II or III?

Current equipment I'm working with:
ASRock Z68 Extreme4 Gen3 mobo
http://www.asrock.com/mb/overview.asp?Model=Z68 Extreme4 Gen3

It has 2 different SATA III controllers. One by Marvell and another by Intel.

- 2 x SATA3 6.0 Gb/s connectors, support RAID (RAID 0, RAID 1, RAID 10, RAID 5, Intel® Rapid Storage and Intel® Smart Response Technology), NCQ, AHCI and "Hot Plug" functions
- 2 x SATA3 6.0 Gb/s connectors by Marvell SE9120, support NCQ, AHCI and "Hot Plug" functions (SATA3_M2 connector is shared with eSATA3 port)

OCZ Vertex 3 120GB SSD

I would prefer to have this in the SATA III Intel controller

2x Seagate Barracuda Green ST2000DL003 2TB
http://www.seagate.com/www/en-us/products/desktops/green-drive-barracuda

I'm wanting to put 2 of these in RAID 0.

My Dilemma:

First Question - If these Seagate drives are in RAID 0, will they even fully saturate SATA II?
If not, then I will just put the RAID config on the SATA II.

If YES, what controller (Marvell vs. Intel) should I put it on. I've heard the Marvell controller is flaky and need to make sure if these drives will even fill SATA II 100%. Please consider my Vertex 3 SSD I'm using as OS Drive in your recommendation.

Much appreciated!

    No, the Seagate drives in RAID-0 do not spin fast enough to saturate a SATA II port.
