I have a new model (2012) Mac Mini. In the system report I'm seeing two ports that show USB 3.0 with max 5.0Gb/s transfer rate and two ports that say that the max USB transfer speed is 480Mb/s. How do I actually check the transfer speed while that file transfers are taking place? I have a Lacie Rugged USB 3.0 device hooked up to the port that is showing 480Mb/s in the system report. Isn't that Mac Mini suppose to have all ports USB 3.0. Is the system report just showing incorrect info? Is there a program I can use to see the transfer rates as they are occurring? Thanks.
