What To Do With 2 SSDs

I have 2 new SSD's but no idea what to do with them.

I have a OCZ Agility 4 256gb and an Intel 320 series 80gb.

I was guessing use the 256gb for Windows OS and maybe sell the 80gb. Is there really any other use for the 80gb? I also have a 2 TB HD, 640gb HD, and Samsung 1 TB hd.

What's the Intel 320 80gb worth? $75 or so?

Would it be worth setting up the 80gb as a cache drive?

btw, i have no idea what i am chatting about but i've heard it being bounced around a few forums.

Do you have a laptop that you can toss it into? Otherwise I would sell it.
