Thunderbolt for 2013 mac book pro pro#
Both the MacBook Air and the MacBook Pro connected on the 2.4 GHz band when I woke them from sleep. The MacBook Air can absolutely do better than this, but one of its problems is maddeningly inconsistent 5 GHz Wi-Fi performance.
First, as a baseline, my old MacBook Air: But I wanted to test a typical use case without any optimizations. This is not the best case scenario, because there is extra file sharing protocol (AFP) overhead and the average speed thus revealed is lower than the maximum speed reached during the transfer, because it takes some time to reach that maximum speed. I transferred a big file (a little under 2 GB) from an older computer connected to the Time Machine using wired Gigabit Ethernet and timed how long this took. I tested wireless network performance using an 802.11ac Time Machine base station. (Which mine certainly aren't at maybe 20 MB/sec.) The SD card reader is now connected over "super speed" (5 Gbps) USB 3 internally, so it should be able to keep up with the speediest SD cards. With USB 3, it can reach 110 MB/sec for sustained transfers. I got a 2.5" bus powered USB 3 hard disk not long ago, which tops out somewhere around 30 MB/sec when used over USB 2. Apple introduced 5 Gbps USB 3 in last year's models, which is a very nice change of pace after having been on 480 Mbps USB 2 for a decade. It may be a while before I have any peripherals that take advantage of this extra bandwidth. The Thunderbolt ports now support Thunderbolt 2 at 20 Gbps. It's a point of pride to have something to connect to every portĮxcept for the surprise addition of HDMI not long ago, Apple has been moving away from special-purpose ports towards multi-purpose high speed ports: Thunderbolt/DisplayPort and USB. Also see the earlier instalments about battery life and CPU performance. This is the third one, looking at the MacBook Pro's I/O ports and wireless networking. Over the next few days, I'll publish my review of the new 13" MacBook Pro here in several installments.
