Currently I have 2 120GB SSDs in RAID 0 on my board's Intel SATA 6 controllers. Is it possible to RAID 0 the 2 Intel ports with the 3rd paty SATA 6 ports (board has 2 Intel, and 2 Marvell SATA 6 ports)? Motherboard is Asus P9X79 Pro
I would be using 4 SSDs, all being the same if the case.
Would this result in a big performance increase if possible? or would the Marvell controller degrade the performance?
Also, would switching from 2 SATA 6 SSDs in RAID 0 to 4 SATA 3 SSDs in RAID 0 net any performance gain?
Theoretically, no, as the interface speed of both is the same. But, a single SSD usually cant even reach half the speed of the SATA 6 port, depending on the SSD (OCZ Vertex 3's in this case).
I'm not concerned with redundancy as i have mechanical HDDs with backups for my data.
Any input on this would be greatly appreciated. thanks.

No, it is not possible.
When you go into the Intel RAID BIOS (Ctrl-I) to create a RAID array you will only be able to chose drives connected to any of the 6 Intel ports.
When you go into the Marvell RAID BIOS (Ctrl-M) to create a RAID array you will only be able to chose drives connected to the 2 Marvell ports.
You can only have 4 drives in RAID-0 if they are connected to the Intel ports.
If you do that your array's Read/Write performance will be limited to 3Gb/s speeds, and your maximum theoretical Read/Write performance will be 1.2GB/s.
Unless you're using your system for video editing, or working with large databases, you won't notice any real-world performance difference going from 2 drives to 4 drives in RAID-0.
