My new MacBook Pro with the Retina Display arrived a couple of hours.
After setting it up I have now tried 3 diffrent USB 3 Portable hard dives and each one is slower then USB 2.
There must be some sort of problem with USB 3 with these new Macs.
I am very dissappointed at this time.
Has anyone else tried a USB 3 hard drive via the new MacBook Pro with Retina Display?
