The notorious red SATA cables - I threw them out long ago. The red

I've never heard of this. I did a bit of searching around and all I
can find is assertions that cable colour doesn't matter for SATA. I
can't seem to find anything about red pigment damaging the copper.
Have you got a reference so I can learn more?
I find it unlikely that the color of the outer sheath of a cable affects
the conductors as they have their own individual sheaths usually of a
different material to the sheath.
It's possible that some manufacturer made cables with faulty individual
insulation and their brand used a red outer sheath. In that case the
color of the sheath correlates with faulty cables but is not the cause
of the faulty cables.
