If those are WD Raptors, all you need to do is set the jumpers on both to 1.5GB/s, connect the SATA connectors, and configure the RAID in the BIOS.

Yes they do - they have jumpers set whether the drive is operating at 1.5GB/s or 3.0GB/s.  At least the 150GB 10,000RPM drives in the OP do...

Positive.  I have the WD Raptor drives in my system.  I also got a couple of 750GB Seagate SATA drives, and I had to configure them to 1.5GB/S using a jumper.

You can't have 3.0 Gb speed when using Raid 0 ? By the way Raid 0 offers very little performance gain in games and applications, it's just good for synthetic benchmark scores.

The WD Raptors only support 1.5GB/s.  That tells you that 3.0GB/s is all hype and no substance.  3.0GB has more theoretical bandwidth, but in real applications not even the Raptors can begin to get CLOSE to saturating a 1.5GB/s channel, much less a 3.0GB/s.   So don't worry about that.  Focus on average access time and throughput instead.  You will find that even with the fastest drives, that is measure in MB/s, not GB/s.

naah, they help almost everywhere: Booting, copying files, loading times in windows, easily writing pagefile, decrease loading times in games, improve loading in games with open enviroment like oblivion.

basically, RAID 0 rocks.
