For instance.... I loaded up their software disk to test the 180gb because of all the errors I was getting. It passed. I then went digging around the other utilities and low and behold my old 100gb drive I've had for a year or so was running at 66. So was the new 180gb drive. I bumped them both up. This seems to have sped up the perceived performance. I did NOT run benchmarking tests on it though.
