Thank you I think I will go with Intel 320 Series SSD to be safe.
You might think about buying a SATA III drive. While it won't negotiate at 6gb, it will allow for some futureproofing should you decide to get a newer machine.
I have an 80GB Intel 320 Series and it works very well. I was actually thinking about the Force 3, but I'm glad I got this. Still as fast as it was on day 1, and I haven't had any issues with it. Intel drives are very reliable.
