USB 4.0 is Coming! And Why it’s Going to be Better than Thunderbolt 3

USB 4.0
Let’s look at how the USB 4.0 might be the most important cable for digital filmmaking ever.

For filmmakers and video professionals, we’ve had a long history with both USB and Thunderbolt cables. As technology has changed and advanced at its current, rapid pace, file transfer, storage and read/write speeds have been a huge part of the digital filmmaking workflow.

And while USB 3.2 was only unveiled a couple of years ago, its peak performance represented 20Gpbs of data transfer speed, theoretically close to Thunderbolt 3 - which itself has enjoyed a great deal of success within the industry as well.

However, recently announced on the USB Implementers Forum, it appears that Thunderbolt 3 may finally meet its match with a new USB 4.0 which (amongst other perks) can reportedly push transfer speeds of 40Gps.

Introducing USB 4.0

What seems of most important to filmmakers and video professionals (along with the crazy two-lane transfer speed) would be USB 4.0’s backward compatibility and multi-connector functionality (USB Type-A, MicroUSB and USB-C) that could see the cable become the de-facto industry standard for years (at least until Thunderbolt updates itself).

No timeline for rollout or release has been reported besides a rough “18 months after the spec” reported. We’ll keep you update as news presents itself including timeline, pricing and availability.

So if I have a USB 3.0 bus and use a USB 4 cable, can I get the 40gbps speed?

You're only as strong as the weakest link. A 4.0 cable on a 3.x bus will give you the fastest available speeds, which would be what the 3.x bus supports. Use a 2.0 cable on a 4.0 device with a 3.0 bus and you get the speed from the slowest part of teh chain, the cable, for 480Mbps.

Thats what I thought, so it may be backwards compatible, but this will not help me with getting the USB 4 speeds. I have to get an upgraded bus.

You do realize USB4 is based off the TB3 spec, right?

No it's going to be the SAME as Thunderbolt 3......if it ends up better than TB3 it's simply because it might now actually end up more widely used.

But all this talk just makes me wanna know MORE about..... Thunderbolt 4....... because I don't think us Apple users are ever going to get back something as simple as user replaceable PCI slots.

I can't even find a PC motherboard with more than 1 USB-C Port. Same for cases. Not looking forward to ANOTHER cable type switch, not to mention...for my Macbook....DONGLES.
