Be VERY careful with the SSDs. Most of the first gen stuff is not very good. Agility 2 is one step down from the Vertex 2. I would not get an agility or vertex. I am not even sure that those older models support TRIM, which is a deal-breaker to me. I didnt think the price difference was all that big for the performance difference between the Agility 2 and Vertex 2, but I have not checked prices lately. You might find a deal on another good model, you should look at the latest reviews.
