hard drive configuration

[NeezyDeezy]

This is my boot drive:

Western Digital Caviar SE16 WD3200KS 320GB Hard Drive
(Serial ATA II, 7200 RPM, 16MB)

And I have a 300gig Seagate ultra ATA/100 7200rpm 16mb cache drive for data.

I am thinking of selling the Seagate in order to buy one of the following:

74 gig raptor

OR

another Western Digital Caviar SE16 WD3200KS 320GB Hard Drive
to run in RAID 0 on the nVraid on my ultra-d with the one I have now

I don't particularly need the extra 250 gigabytes that comes with the WD now, so I'm having a hard time deciding which to buy. The Raptor is cheaper and would just hold my OS and all of my apps... How much faster would the single raptor be compared to the caviars in raid?

Which would you opt for? Or maybe suggest a 3rd option? Thanks!

I'm under the impression that a set of 7200 rpm drives (config'd RAID 0) will outperform a Raptor single drive in any usage.

My 160GB WD 3G drives in raid-0 are a good bit faster than my 36gb raptors in raid-0 were.
