Thunderbolt v1/v2 Expansion & Connectivity Options

Thunderbolt (codenamed Light Peak) is an interface technology developed by Intel and adopted by Apple in 2011. Modern Apple Mac computers now only have Thunderbolt and USB3 ports with FireWire ports being dropped altogether. The newest Mac models with Thunderbolt 2 have limited internal expansion capabilities. This article is a list of some of the best external Thunderbolt expansion options available. We'll regularly update the article with up-to-date product information so please do check back.

Thunderbolt cables are available as copper or optical and Thunderbolt carries PCI Express (PCIe) and DisplayPort (DP) as one signal alongside electrical power, transmitted over one cable. Up to six peripherals can be supported by one connector through various topologies as long as the expansion device has a Thunderbolt connector on it itself otherwise the device becomes the "end of the line".

There are currently three versions of Thunderbolt:
  • v3 - up to 40Gbit/s - supports 2x4K monitors and up to 100W power (launched 2nd June 2015 with USB-C connector)
  • v2 - up to 20Gbit/s - supports 1x4K monitor (launched 2013)
  • v1 - up to 10Gbit/s (launched 2011)

Q. Which Mac do I have?
A. You can check "Processor", "Memory" and macOS/OS X/Mac OS X "Version" by going to Apple menu > About This Mac > Overview tab if necessary (hint - clicking on the version number will give you the "build" number).
A. To check your Mac's "Model Name" go to Apple menu > About This Mac > Overview tab if necessary > check for the computer name in the top line e.g. "MacBook Pro" (this can only be checked with OS X 10.7 or later)
A. To check your Mac's model date version go to Apple menu > About This Mac > Overview tab if necessary > check the details after the Model Name e.g. "Early 2015" (this can only be checked with OS X 10.7 or later) - to be more specific and exact you can check what "Model Identifier" your Mac has by:
  • If you are running Mac OS X 10.6 or earlier go to Apple menu > About This Mac > click the "More Info…" button > (the System Profiler application will open) select "Hardware" in the top left > check what it says for 'Model Identifier' on the right.
  • If you are running OS X 10.7 or OS X 10.8 go to Apple menu > About This Mac > click the "More Info…" button > (the System Information application will open) select "Hardware" in the top left > check what it says for 'Model Identifier' on the right under 'Hardware Overview'.
