I think all of the cables I have seen so far are pretty much the same, I have never seen anything specified as a SATA I or II cable - further, I don't think the color means much either, kind of like network cables that come in grey, blue, white, yellow or what ever. I have never seen those colors though, I usually see red and sometimes black but the black ones I have seen look kind of cheap - use the one that appears more robust!
