If you ever transfer large files to or from a Thunderbolt-equipped MacBook Air or Retina MacBook Pro where wired networking is available, you probably want Apple’s new Thunderbolt to Gigabit Ethernet Adapter.
I ran some speed tests with zPerf from the 15” Retina MacBook Pro to my Gigabit-wired Mac Pro:
- Apple USB Ethernet Adapter: 94 Mbps (it’s a 10/100 device, and only USB 2)
- Wireless via 802.11n: 118 Mbps (to the newest AirPort Extreme, 15 feet away)
- Thunderbolt to Gigabit Ethernet Adapter: 941 Mbps
