Raid 0 vs. storage

I'm building a computer and I'm not sure if I want to go with 2 36.7 WD Raptors and set them up as a raid 0, or if I want to go with 1 36.7 Raptor and then another WD 80gb for storage.

What are the benefits of raid 0 in the 1st setup?

Would it be possible to set up a raid 0 with the Raptor and the slower 80gb?

What are the risks of data loss in a raid 0 array?
 
If you want to boot from the raid array, you'll have to be using either a pci raid card or a mobo w/ a raid controller built-in.

Raid 0 can provide a nice boost in performance, depending on your usage patterns. The caveat is there is an increased risk of data loss. Basically, if one drive craps out, you lose data on both.

Most Raid card/chipset manufacturers will tell you that it's best to use identical drives in an array. NTM, if you DID setup a raid 0 w/ 36.7g and 80g drives, you would only get a raid volume of 36.7x2 gigs, or around 74 gigs. That's just the way it works.
 
From my experience with 2 Raptors in RAID 0, I've not been able to boot from them with either a PCI controller or on-board controller. Consequently I use an IDE drive for booting, swapfile and storage, and the RAID contains the OS and installed programs.
