USB 3.2 specification to double transfer rates, no new cables needed

The USB 3.0 Promoter Group on Tuesday announced an incremental update to the USB standard that’ll enable faster transmission of data across existing cables.

USB hosts and devices were originally designed as single-lane solutions but as bandwidth demands increased, it became increasingly apparent that something would need to be done to scale performance. That’s why multi-lane support was built into USB Type-C cables.

With the USB 3.2 specification, new hosts and devices can be designed as multi-lane solutions to take advantage of the extra lanes.

The USB 3.0 Promoter Group, which is comprised of Apple, Hewlett-Packard, Intel, Microsoft, Renesas Electronics, ST Microelectronics and Texas Instruments, notes that new devices can support up to two lanes of 5 Gbps or two lanes of 10 Gbps operation. A USB 3.2 host connected to a USB 3.2 storage device, for example, will now be capable of data transfers of over 2 GB/sec. With two 10 Gbps lanes, performance is effectively doubled versus what is possible today.

Just to reiterate, because existing USB Type-C cables already support multi-lane operation, no new cables are needed to realize the faster speeds. What’s more, the USB 3.2 spec will remain compatible with USB 3.0 and earlier devices.

The USB 3.2 specification is currently going through a final draft review phase. A formal release is expected ahead of the USB Developer Days North America event scheduled for September.

I swear to god if they pull off another USB 3.1 Gen 1...

Goddammit. Well, at least the MINIMUM for USB 3.2 is 10 Gbps.

I wonder though, how many cables will actually be able to transfer this data at the 2GB speeds?

RIGHT even more confusion and possible scams coming up.
Thunderbolt 3 is able to transfer up to 40 Gbps so why the need for yet another so called more speed.
There is nothing for sale what makes use of these speeds at all.
In fact there are no available devices for thunderbolt 3 hell there are hardly any devices with thunderbolt 2 ... so why this silly new not being used so called new standard. I am pretty sure that you will not see any device in the coming 5 years which will make use of those speeds. All usbstick drive makers just started adoption usb 2 ssd like drives before they switch over to real usb 3.1 speeds your another 10 years further.
And the endless scamming companies who sell usb sticks which are sold as usb 3.1 device while they actually are selling usb2 speed devices. This whole new standard is made for the ultimate scamming... I really hate it

I think most cables will not go faster than usb2 speeds in general, you will however see many companies selling bad cables as usb 3.2 compatible. Look at the google guy who showed that most cables on the market are in fact a risk for your devices.
There is so much crap being sold its unbelievable, before one post I bought a good brand... it does not matter if its has a large company name they often buy them in bulk from cheap chinese makers who do not care much about that.
