You kind of answered yourself. 5 gbps is the absolute max
Speed of sata 1 is 1.5 Gbps Speed of sata 2 is 3 Gbps
The maximum speed that can be achieved using a coax cable for internet connectivity is typically around 1 Gbps (gigabit per second).
1 Gbps
The maximum is 1 Gbps (CAT-5e, CAT-6), the maximum distance without attenuation is 100 m.

I assume you mean flash drive/USB memory stick. The latest speed is either 3.2 Gbps (400 MBps USB 3.0), or if you're lucky there are now Thunderbolt I/O drives that can reach speeds of 10 Gbps (1.25 GBps).
You can travel at a maximum of 50 MPH or Km\h
