Round Cables slower then Ribbons?

I hear it all the time but then some people say otherwise. I'm just getting confused. So if I could get everyone's opinion on these round cables, I'd greatly appreciate it!

Thanks.

But the whole idea of 80 pin cables is that every data cable is seperated by another cable, making crosstalk less. But now with rounded cable, all the cables are seperated and the bundled together. So, my opinion is that in a perfect world this wouldn't matter. But it's not. A harddrive works on the same principal as a network card, doesn't it? It will try to send the data (with error correction)untill the data is on the other side. The more errors, the longer it will take. So the transfer rate will still be the same, but the actual data/files coming out will be less. Any electricians have a comment on this??? I know some rounded have some foil insulation that will help.

Actually airflow through the case and data corruption are the two main purchasing plus's, its conductors are basically copper wire, one will not transfer any faster than the other, the biggest advantage of round cables is not restricting the airflow through the case like flat ribbon cables do, and properly shielded round cables have virtually 0% data loss, some of the best round cables I've seen and the type I use are the Antec cables, they're not only twisted and shielded they have an included grounding wire that runs through the cable that grounds to the case.
