USB 3.2 Specification Published and Announced
A while ago there was already word out on the street that the USB Focus group would be announcing a new draft for upcoming USB 3.2, that has now been finalized and published. To keep things really simple, we're doubling thing up once again.
Where USB 3.0 aka 3.1 Gen1 was capable of 5 Gbps connectivity, USB 3.1 Gen2 did 10 Gbps. USB 3.2 will double that up-towards 20 Gbps. Divide it by 8 bits and that would be 2500 MB/sec from which you need to deduct encoding and errors. There is a distinction though as it is based up-on two-lane operation as tweakers.net spotted today.
Key characteristics of the USB 3.2 solution include:
- Two-lane operation using existing USB Type-C cables
- Continued use of existing SuperSpeed USB physical layer data rates and encoding techniques
- Minor update to hub specification to address increased performance and assure seamless transitions between single and two-lane operation
So basically using two 10 Gbit/s lanes you get towards a throughput of 20 Gbps. Obviously you will need a host and client connection that is compatible with the new standard. Current USB type C cabled would be compatible if they have been certified for 10 Gbps SuperSpeed USB. If you like to do some reading, there is a 548 page document available on the new 3.2 Spec, download here.
| USB version | Speed | Encoding | Connectors |
|---|---|---|---|
| USB 2.0 (incl usb 1.0 and 1.1) | up to 480 Mbps | 8 / 10bit | Type a, b (mini, micro), c |
| USB 3.1 Gen 1 (SuperSpeed Usb) | up to 5 Gbps | 8 / 10bit | Type a, b (mini, micro), c |
| USB 3.1 Gen 2 (SuperSpeed usb Gbps) | up to 10 Gbps | 128 / 130bit | Type a, b (micro), c |
| USB 3.2 (SuperSpeed usb 20 Gbps) |
up to 2 lanes 5 Gbps |
128 / 130bit | Type a, b (micro), c |

This is getting annoying already. I hate what industry does nowadays by moving at such a fast pace that even consumers cannot keep up.
Why they don't just release USB 4.0 with 1Tbps, with 1KW of power and call it a day for the next 10 years? They like to create one million revisions and release them once a week, like somebody would care.
I know that shareholders are crazy for more money and that new stuff drives the market and the sales in general, but come on! Take a vacation, enjoy some wine and live the life. Computers from 5 years ago are still very much ok and USB 3.0 is still plenty enough for pretty much everything you could possibly need.
Um......you might want to get interested in a different hobby. This is a technology forum. Technology advances fast, many times faster then the industry. Like, that's exactly what is supposed to happen with technology.
How is having not implemented new specs moving forward....
Motherboards still have pointless 2.0 slots, usb 3.0 only, a few gen 1 3.1 slots and a single type c connector.
That would be like calling the current existence of 16k displays 'moving forward' when no one even has access to them, let alone could afford them.
It will move forward when the legacy garbage doesn't comprise 80% of all usb slots on a motherboard.
None of this has anything to do with why technology shouldn't move forward. If you're complaining that there is slow adoption rate, or that older generation stuff is still being used, then complain about that to the people who are still utilizing or under-utilizing said product, not the people advancing the technology itself. It's up the people who are developing USB to advance it, it's up to everyone else to utilize it.
Have we got to the stage now where we might as well use USB instead of Sata? XD
Why why why has Sata not been increased in so long >.> might as well use USB or thunderbolt for SSD's since Sata bottlenecks them.... 2500 MB/s comes close to m.2 slot speeds XD
^This. Y'all complaining about USB advancing too fast (lol?) Whereas other areas its not moving fast enough.
The USB 3.1 generations and 3.2 should have been released at once. If they have further specs planned for the next say, year, they should wait and incorporate it together.
That's not how technology advancements work. If they did, we'd never get new technology, because "Well we'll just wait till next year to have something better" for eternity.
What drugs are you on?
Please can you just make one USB port that fits all connections and devices and stop this BS.
The biggest problem with this idea is that it'll take a long time before USB type A connectors are gone. USB type C connectors are the future, everyone should understand that, but that doesn't automatically mean type A just disappears suddenly. There's far too many type A connectors to simply decide to not include them on laptops/PCs/etc.
In 10 years, i'd expect that motherboards might have more type C connectors then type A, but even that i wouldn't be surprised if it doesn't come true. People, not companies in this regards, are slow to change. If given the chance, and you have type C, and you went out to buy a new mouse today, and you saw one with a type C and a type A connection, even though you can support both connections, 99% of people would buy the type A, because it's what they know, and they can justify it with stating if they use it on a different PC later on they don't have to worry that PC might be older and have no type C connection. Because of this, adoption simply will be slow.

Exactly, but, alas!, only from the logic's point of view. Which is not a point of the greedy bastards called companies - they profit more by cutting the bread into thinner slices, pouring milk into the smaller cups and selling "refreshed"/"refurbished" ideas and solutions every now and then...

And I just got USB 3.1 on this new motherboard I bought couple of months ago, this technology is going not just fast but oddly.

It's what short USB cables are for. Just buy some short USB cables that meet the specs of the port (USB 3,/3.1 etc) and run it over the top of the case. You can even affix them to the case so you can plug devices in one hand.
