Will SATA II cables from last install transfer at 6gbs for the new SATA III install.

I am building a new computer. The new motherboard and SSD are SATA III. I have some SATAII cables left over from my previous build that I would like to use, if they are capable of 6gbs transfer rates. Are SATA II and SATA III cables constructed the same? I have searched and found conflicting information. Thanks for the help!

Let’s first say that when we started this, we were absolutely sure we’d see a difference. Afterall, moving to an authentic SATA 6Gb/s cable cleared up our problems the first time right? Wrong. As we worked our way through the first few cables, we began to realize that the SATA I/O did its work when it first put together the spec for cables. There is virtually no difference between a brand-new SATA 6Gb/s marked cable made this year and one produced nearly eight years ago as far as performance goes. Expensive cable, cheap cable; long cable, short cable—none of it seemingly made a real difference. If anything, the minor variances in performance can be attributed to variances in the benchmark or the SSD.

Our results confirm that despite the faster hardware available today, there is still no performance difference between SATA 3Gb/s and SATA 6Gb/s cables. The SATA 3Gb/s revision only supports transfer speeds around 300MB/s, yet we saw transfer speeds up to 500 MB/s with each cable that we tested. This clearly shows that the SATA revision designator on cables is mostly just marketing and has no bearing on the actual performance the cable can provide.

Thanks my friend.
