Default Internal SATA cable speed

Does anyone know if there will be a significant difference in performance
between an internal HD SATA cable that works at 3G bits/sec and one that
works at 1.5 G bits/sec? Theoretically should be twice as fast but then there is HD and buss speed to consider.

I bought three 1.5 G bit cables on-line because I was told they were the
fastest on the market, then I found the 3 G bit ones. I'm thinking not worth
the hassle to pay to send these back and order the faster ones.

Unless your drive can write/read over ~180mB/s, I doubt it's an issue.

The cable that you bought can do 3.0Gbps as well, but you won't find much of a difference, since the data speeds won't exceed much from 1.5 to 3.0.

Current rotational based hard drives (vs SSD's) can't really saturate a SATA connection, no. And since SATA is point to point, i.e. one drive per cable = one drive per channel, that 1.5 speed is dedicated for each drive.

SSD's are a little more hazy though - even "general performance" SSDs can quickly saturate a SATA 1.5 controller, so at a minimum, for best performance, I'd have a SATA 3 capable board.
