I have a 2010 13" MacBook Pro. I bought a FW800 enclosure for my 500GB Seagate 5400rpm HD. In OSX using Path Finder to test transfer speeds I get around 40MB/s. Pretty good. Not as fast as it should be given the drive and FW800's possible speeds, but acceptable. When I switch over to my boot camp partition with Vista Ultimate installed I get 4MB/s. I can't figure out why I'm getting such slower speeds with Vista. I did the tests using the exact same files. So what am I missing? How can I get the transfer speeds I should be getting in Vista?
