Hi there,
First, my apologies if this post is in the wrong place or I have not posted right, this is my first post as a new user so PLEASE be gentle
OK first off I will list my current set up :-

Thermaltake X-aser midi tower case
Asrock A790GXH/128M Motherboard
Kingwin 800w Mach 1 PSU
2 x Western Digital WD3200AAKS-00V1A0 ATA Device (320GB) Hard drives
AMD Phenom II 940BE AM2+ CPU
Nexus FLC-3000 Cooler
Crucial Ballistix DDR2 4 GB : 2 x 2 GB Memory - DIMM 240-pin - 800 MHz ( PC2-6400)
ASUS Radeon HD 4830 Video Card EAH4830 512MB 256-bit GDDR3
WINDOWS 7 64bit O/S

OK, so here's my problem
I would like to use my two Hard Drives in a Raid 0 configuration but I am unsure on which drivers to use to achieve this.
My windows 7 64bit is an upgrade disc so I have to first install my Windows XP 32bit disc followed by the windows 7.
So which drivers do I use for Raid, XP 32bit or Vista 64bit ?(I assume Vista 64 bit are the same as Windows 7 64bit as there doesn't seem to be an update on the Asrock SITE)
I have never set Raid up before, so any other advice, tips or comments would be most welcome.
I am happy with my current PC as my graphics and psu are both mildly overclocked but stable with good temps, and play the games I enjoy with no problems.
My next upgrade will be a SSD for my O/S but until I can afford this, the Raid SEEMS the next logical step to take to squeeze a little more performance out of my Hard Drives.

Many THANKS in advance

Marillion
