Using Windows to Raid two Raid 0 drives.

I was just thinking about this, and wondering if it would be possible, and if it would actually provide any speed increase.

So to clarify:
I'm wondering what the outcome would be if you had four drives (let's say SSD drives, for example), and you set them up in your firmware RAID as two RAID 0 arrays, of two drives each.
Then install Windows (would have to be on a separate, 5th drive. Also, you could do this with Windows already installed).
In Windows, create a new striped volume using the two RAID 0 arrays that you just set up in your BIOS (well, the RAID firmware screen).

Would this bump up the sustained read/write speed, since that striping is occurring in two ways? Would the potential overhead negate any speed gains?
I don't quite have the hardware to try this out, so I'm wondering if anyone has drives sitting around, and could try it. (I have 3 Crucial C300 64GB SSDs, so I could try it if someone has an extra one of these they don't need, and wanna send it my way haha).

Let me know what ya'll think. Thanks!

You would be creating RAID 0/1. You would see the performance benefits of that RAID level barring limitations of the controller.

I don't think so.I've tried it with a 2-ssd RAID 0 on Areca ARC 1261 + IRST 2-ssd RAID 0
 
A modern SSD on it's own is pushing the limits of the SATA interface, so I don't see benefit in doing this. One thing you could do with an idea like that is to combine the benefits of RAID 1 and RAID 0, but that has already been thought of, RAID 5, and pretty much any current Chipset/SATA controller supports this.
