Ouch! USB C

20 gb/s (Bandwidth negotated)
Up to 100 W of negotiated power (Up to 20 V at 5 A)
Same small connector at each end (can be used on the tiny devices too)

EE Times said:

The end result is that -- depending on its capabilities -- sometimes a device may transmit both power and data; sometimes it may receive both power and data; sometimes it may transmit one and receive the other; and sometimes it may dynamically switch between all of the different possibilities. Once again, this is all subject to negotiation between the various devices.

It can use unintelligent cables and be USB 2.0 compatable.

So what exactly is the point of 20 Gb/S transfer rates when most everything we have now is still rather far from hitting USB 1 and USB 2.0 realistic limits?

Just curious being my best USB SSHD's never get much over 15 Mb/s rates on much of anything in real life normal transfer activities.
To be honest Most of my USB stuff is lucky to see 4 - 6 Mbs/S sustained rates and my interconnected home network between the laptops and computers rarely transfer at much over 20 Mbs/S despite everything now having system supposed capacities between 100 Mbs/S and 1GBs/S.
