2x 500GB in RAID vs 1TB Single HDD

[StarSolitude]

I want whats best for performance as I'm a gamer. What would be better:

2x Seagate Barracuda 7200.12 500GB SATA-II 16MB Cache

or

1x Samsung SpinPoint F3 1TB SATA-II 32MB Cache

Basically, RAID-0 with 2x 16MB Cache HDD's or single 32MB Cache HDD, would there be much of a performance gap? Keep in mind it is cheaper to just get a single HDD. Never done a RAID before and my knowledge of hard-drives is lacking...

I'd just get the larger 1TB, or even the 7200.12 1TB if it's cheaper.

So RAID isn't worth it, is what you're saying?

Hmm, I'm still not so sure. Paying more money just for a few seconds off loading times in games... But then again, RAID will also help all over the board, for example no stuttering when opening photos and MP3's, and faster defrags?

Over the course of time, it would be quite nice...
