What do you need? Are you looking for performance or resilience?
Here is a brief summary:
I asked myself the same question recently. I wanted decent performance but
not at increased risk. In the end, I just bought a Smasung HD501LJ drive.
It's cheap, it's quiet, and in Custom PCs recent tests it all but matched
the WD Raptor 150, and I back it up regularly to other disks too.
I'm definitely in the power user bracket; but this drive on it's own is more
than fast enough. If I make regular backups, I have resilience. If my disk
failed now, I'd obviously lose any work up until my last backup, but in my
case that is not an issue.
The solution that has been offered to you sounds reasonable. Raid 0 will
give you a slight performance improvement (but it's often over-rated), and
you will be able to back the volume up to the 3rd disk. I'd just question
whether the Raid 0 is worth the theoretical risk. If you have two slow
drives you'll probably find it is outperformed by the faster 7200 SATA II
