Standard data transmission speeds
The following table shows the data transmission speeds of common interfaces.
Note that you should always use the slowest interface for reference. So for example, if you copy a file across a gigabit ethernet to a drive connected via USB 2, you should refer to the USB 2 speed only.
Also bear in mind these are theoretical maximums, and real-world speeds will vary greatly. For example, although 802.11g has the same theoretical speed as 802.11g, the latter is far more stable in the real-world.

I thought Thunderbolt was 10k Mb/sec in each direction at the same time, not 20k.

You’re correct. I’ve amended the spreadsheet.
