USB4 is coming. Soon.

Well, we didn’t see this coming – well I didn’t anyway.

USB4 and its specifications has been announced even before USB 3.2 is even out. Pundits are suggesting it will rival Thunderbolt 3 for speed.

USB 3.2 was supposed to be the one that brought back together the mess that was USB – what with the original, plus USB 2, then 3 then USB-C and so on and so on.

I don’t know about you, but I there are so many different types of cables around, to keep them separate I use one of those fancy belt hangers on the back of my studio door to drape each flavour on, so they are easy to differentiate with one end always the same an’  all.

USB 3.2 was supposed to bring transfer speeds up from the 5Gbps of ver 3.0 to 10Gbps, but there were also implementations and variations to give us SuperSpeed USB at 20Gbps with Type A, MicrosUSB AND USB-C variants.

Now, USB4 (not 4.0 according to the standards body, the USB Implementers Forum, but plain old 4) apparently will give us 40Gbps and use existing USB-C cables plus will be backwards compatible to USB 3.2, 2.0 AND Thunderbolt 3.

Whew. That’s that sorted then. But them in the know reckon we won’t see any USB4 devices until well into 2020, if not beyond.
