[Jeremy Garchow] “[Douglas K. Dempsey] “Re: USB 3, I was told the one downside was the fact that it’s not full duplex, so while great for a read OR write, less than perfect for constant read/write that happens during editing.”

I’ve always heard that USB is no good either, and USB and Macs up until this point has been a pretty dubious connection. The intel USB3 implementation seems to be pretty good, fast, and different than shitty Apple USB2.

I’ve been testing it with mobile editing on a new laptop, and it does just fine with 1080 to 4k ProRes/XAVC.”

That stems back to the way USB was initially designed. Using an oversimplification, USB moved data in “Buckets” while FW was a continuous stream. That’s why FW was preferred. Anyone using early USB drives experienced the inconsistent delivery of higher demands of video. Great for backing up files though.

Obviously USB has improved, and USB3 is seriously useful. Being bi-directional (as Lance pointed out) is just one of the reasons…
