    I've heard many reviewers state that there is no difference between a SATA 2.0 cable and a SATA 3.0 cable other than the marking on them. I have heard others say that there are differences. I'd definitely like a definitive answer on this.

    Found this from SATA-Io_Org:

    They definitely mention that SATA 2.0 cables may not live up to SATA 3.0 drives, but there doesn't seem to be a set standard for the cabling, at least in that document. Is there any other information out there?

    Shielding and how it's shielded and actual wire construction is the big issue.

    Indeed, if you put the two cables side by side there is a difference. It seems with a Sata 6gbps cable that it is split in two lengthwise. What it actually means in terms of how it works I have no idea.

    Yeah, I'm not sure, exactly why, but 6 Gb/s cabling is a bit thicker than SATA2.


    That said, most users do not even ahve devices that should notice any real differences, unless teh cables are real garbage, but I thikn this may actualyl end up playing a role specifically with SSD speed, as SSD's reach over 500 Mb/s.
