Which SSD drive should I use for recording?

I am making a new gaming pc and I need some help with the drives.

I am planning to use Fraps to record gameplay and I know SSD is the way to go, but will it make a difference if I record on to my primary drive (SSD) or shall I get a separate drive for recording.

So either this:
256Gb Vertex 4 SSD for OS and Recording
1TB for storage

Or:
64Gb Vertex 4 SSD for OS
256Gb Vertex 4 for Recording
1TB for storage

Also are my SSD's good enough for the job. I plan to record in 1080p.

Thanks in advance.
