Pros: The fastest HD out there. I have two 150's in a raid config and my pc is so much faster than when I had my twin 7200rpm drives as my system drives. I was waiting for the cost to go down so when I say it for under $200 I had to jump on it.

Cons: Size? cant really complain about noise or heat. Just make sure that you have a good fan going over it.

Overall Review: I was waiting for the cost to go down so when I say it for under $200 I had to jump on it. It really does make a noticeable difference.
