Many will say that in real world application the gains from RAID arrays are minimal, though it seems many here run RAID 0. I prefer RAID arrays myself mostly for the data protection of the mirror configurations - Something you don't have in RAID 0. RAID 5 is a good compromise between speed and protection, though at that point you only need one more drive for RAID 10. With two new drives a RAID 0 setup SHOULD be reliable for a number of years, though no guarantees.
RAID arrays aren't for everyone. Thay are somewhat difficult to setup, though if you can read a manual and have some patience, you can setup a RAID array.
Your MB has the Drive Xpert option for RAID setups so you have a choice of how you wish to configure it, with Drive Xpert, or the conventional BIOS/southbridge method. Both achieve the same thing, a choice of RAID 0, 1, 5, or 10. The conventional method is a fairly involved procedure and you'll need a floppy drive. The Drive Xpert method requires three drives to setup the RAID on two drives, the third drive is needed for the operating system. You start with a conventional installation on the third drive then migrate the operating system to the two raid drives via software leaving you with the option to use the third drive as a data drive or remove it and store all data on the RAID array. I've used both methods and have settled on the conventional BIOS/southbridge method. Maybe more complex, but doesn't require the extra drive and I am familiar with the steps involved. All instructions for both methods are covered in your MB manual.
