SAS vs SATA drives with RED camera

Hello,

I want to know if my SAS Raid 5 system is that much faster for video editing, using a Red cam, than the standard SATA configuration for hard drives.

I welcome real world experience, your trials and errors, so please let me know what your doing, what you think, what works and any suggestions. Thank you.

I have a new Mac Pro 2009 Nehalem.

1) 7,200 rpm SATA 1TB hard drive.

VS

2) 3x 15,000 rpm SAS 450GB promiss Raid 5 w/ Apple RAID card (unable to use boot camp)

*Primary use: Editing footage shot with the RED camera.

In "Log & Transfer" I'm limited by the REDs firewire 800. So the drives shouldn't make a difference here.

Copying files: SAS is gonna be 5x faster or so it seems.

Editing in Final Cut Pro 7: Heard hard drives make little difference, it's all about processor?

Coloring in COLOR: Heard it's all about the GPU & the Processor, again, no real world experience to make this up.

Final Output: I'll probably just leave it in PRORES HQ, this part I'm willing to wait on.

THE REALLY REALLY BAD: no boot camp with Apples RAID card.

I'm exited to see what you guys think out there. The apple RAID card just isn't going to cut it, I must have boot camp. I was thinking of selling the RAID card to someone who could really use it, maybe someone doing server stuff, with the SAS drives and getting 10k raptor drives and making a software raid? Or maybe someone else out there makes a RAID card that works with boot camp? Dunno

Your experience and advice is much appreciated.
