I just got Vista ultimate and am considering a raptor drive for it. If I can get a new 74GB Raptor or a used 150GB for the same price, which would I be better off with, assuming the used one still has at least a couple of years warranty left. I dont think I will really need the 150GB immediately, but I'm sure at some point in the future i would use that space. Any suggestions or pitfalls I should watch out for in a used drive? Thanks.
