Spinpont drives have gotten some of the best benchmark tests, and have good ratings from users. A comprable drive would be the ED Black series. The Blue is a bit slower. COLGeek is correct that you will really only see a small difference in speeds, but I think the prices are the same so why not get the marginally better one?
IMHO, I'd go with the Spoinpoint, and that's what I picked for my next drive upgrade after doing a bit of research.
