Some people may assume that Firewire and Thunderbolt are the same, but they are different from each other. The speed of these two is different. The max of Firewire is up to 3.2 Gbps while the maximum speed of Thunderbolt is 10 Gbps. Take note that you can connect to different types of interfaces depending on what you are using.
FireWire is generally used by people whenever they want to do some recording because this is higher than the expected 2.0 Gbps that the USB connector usually has. FireWire and Thunderbolt will not require the exchange of too much data before it would work.
