I have my Mini for almost one year now, but didn't have any USB3 drive until now. I bought the Lacie Minimus USB3 3TB. As many know, USB2 on the Mac isn't that fast, and I was kind of worried that USB3 wasn't that fast, but boy! I was wrong! My internal HDD got this with the blackmagic test: (averages - high) W: 102 MB/s R: 102 MB/s And the Lacie go this: W: 159 MB/s R: 155 MB/s I had a small hickup at the first time I plugged it, it was getting USB2 speeds, and then I read that the bus will take the speed of the first devices plugged, I just swapped ports and it gained the USB3 speed. Does it show that I'm happy? Anyone else with happy encounters with USB3?
