Now that both the MacBook Pro Retina Display and MacBook Air ship with USB 3 I was curious to find out which was actually faster? Going with my existing Firewire 800 drives and the Thunderbolt to Firewire adapter or USB 3 drives. I did searches online and really didn’t come up with much in the way of current data or test. Most of what I found was comparisons to USB 2 or tests done before Macs had USB 3 built-in. Since I couldn’t find the data I wanted, I decided to do my own tests.
Making it fair
I wanted this to be as fair as possible. That meant that I didn’t want to use two different drives. Ideally I would want to test the same drive that has both Firewire 800 and USB 3 built-in. That configuration isn’t as easy to find as you would think on a portable drive. I found two: LaCie’s Rugged 1TB (which I’ve used in the past with no issues) and the Oyen Digital Mini Pro. Since I was looking to have a smaller enclosure, I decided to give the Oyen Digital a shot. It was also a few bucks cheaper.
For the benchmarks I went with the Free App – BlackMagic Disk Speed Test.
I recorded my results in the video above.
