USB3 implementation MacPro Tube vs MBP Retina

[Craig Seeman]

Or another way to put it is that the MacPro, Thunderbolt PCIe had a higher priority given the greater potential utility and demands. Only so many lanes to go around.

It wouldn’t be uncommon on a small live streaming job to use two thunderbolt and one USB3 port for 3 HD camera in and then recording ProRes to an external USB3 drive.

There’s less necessity to do that on a MacPro, given the number Thunderbolt ports… but if you’re using the same peripherals and trying to use the MacPro, which may see more on location use given its small size, you could find a bottleneck if you’ve been using two high throughput USB3 devices. Easy to work around though.

Basically it could happen unless one is aware of the limitation, hence, my reason for starting this thread.

Test it and report back!!!

So you’re not “just sayin'” then?

My guess it would be rare for most people and for those who might bump into this there’d be easy solution by replacing USB3 with an equivalent Thunderbolt.

The limitation does seem to be real and while OWC didn’t give me the tech explanation they said I’d be better off with Thunderbolt 4 bay for JBOD use.

The difference between USB3 on MacPro and MacBook Pro is real and that’s certainly not “just sayin’ ”

Then maybe you should stand by your words and not use that.

I made clear the concrete technical differences in my first post.
The debate was over there was real world impact, as I see it.

For most people, maybe not.
The wall is real and there are some workflows that can hit it though, maybe not for editing though but that’s not the only video work I do.
So for editing, just sayin’
… but if you need live access to multiple devices on USB3, you can do things on MBPr that can’t be done on MacPro.
