I am getting a 120 GB Western Digital with an 8mb buffer in soon and I need a controller card. I wanna get a card with ATA 133 abilities in case I ever decide to get one of those. What is the best card and where can I get it at a good price?

Also, what will I get the best performance at (or will it be the same)...On a chain with either a 40 GB 7200 RPM or a 9 GB 5400 RPM...or would it be better by itself off the controller? Please help me out....
