MA790X-UD3P - RAID or G-SATA RAID?

[Prodromoi]

I'm planning on setting up a RAID array (two discs, RAID 1) on a MA790X-UD3P board, but I'm very confused reading through the procedure in the manual - specifically on the difference between:

p73 Configuring AMD SB750 SATA controllers..
and...
p75 Configuring GIGABYTE SATA2 SATA controllers.

Basically, what's the difference and why should I choose one over the other?

I've configured (normal) RAID before on a non-Gigabyte mobo, but I don't get why the Gigabyte RAID works through the G-SATA ports while the AMD RAID works through the six normal ports.

Is one 'better', and if so why?
Is one more 'recoverable' should I need to take the hard drive to another computer?

Thanks in advance.

The only difference that I can see is that the ordinary SATA2 shares the PCIe bus whereas the GSATA doesn't. That means in theory the GSATA might be quicker because of no bottlenecks. See page 8 in your manual: http://download.gigabyte.eu/FileList/Manual/mb_manual_ga-ma790x-ud3p_e.pdf

Hi,

No real difference with regard to the way that RAID or SATA 2 works on the different ports as far as I have noticed. The GSATA ports are generally Gigabytes own implementation of SATA/RAID rather than a 3rd parties such as AMD.

OK, thanks for that.  So theoretically the GSATA configuration should be quicker because of the dedicated channel...

However, should I have a disaster that I need to recover the data from the drives following - specifically a motherboard failure, will taking the the GSATA route cause problems because the RAID array/data/MBR/whatever will be proprietory and less commonly "understood" by other motherboards/RAID controllers?

I am really not sure on that point but I would feel that it would conform to the various standards involved regardless of the chip implementing it.
