More unique is impossible as unique means one only.

Useful though - my house is one of four that are 'identical', but there are
small differences, e.g. Where I put a large loft-hatch in my house would be
impossible to do exactly the same next door due to a major joist being about
an inch along.
This means that each of the four is unique (in more than piffling details)
but the one with two rooms knocked into one is 'more' unique.
It's the difference between 'hard' terminology (which should always be used
for technical subjects) and heuman 'fuzzy' terminology. That's why computers
will never quite manage to be like us, although the Turing test was passed
many years ago, when 'help' lines were first 'manned' by automata
indistinguishable from computers. However, the other way round...

No, both power connectors work.

But the recommendation is not to connect a SATA 15 pin
and a Molex 4 pin at the same time. And the "corner case"
for this is so obscure, it's hardly worth mentioning.

Normal I/O looms will be using the same 12Vn output for
powering drives. All the power will be coming from the
same 12V and there won't be a loop.

There were a few supplies with four independent 12V transformers
inside. This would give a 12V1, 12V2, 12V3, 12V4 supply. It was
very confusing as to which supply went where. The owner of such
a supply, was well advised to find a block diagram of the looms,
and make sure it was understood before installing the supply.

If (somehow) one drive power source ran off 12V3 and one off 12V4,
you wouldn't want current flow between the two connectors,
because it could burn something (burn the pins on a connector).

It's for that obscure reason, you're not supposed to plug
in the SATA 15 pin and the Molex 4 pin on a drive like
that, at the same time. The chances of that happening
are pretty damn close to zero (cross-flow).

Now, a person *could* put two separate ATX supplies in
a machine, and run 12V from one supply to the SATA, and
12V from a second supply to the Molex. So that's another
way you could encourage cross-flow.

I think Sam E was just saying that, if that is the case, VanguardLH's
word "just" is incorrect.

Which I and others already previously mentioned. I only replied in THIS
subthread to Char's inquiry about SATA drives with Molex power
connectors.

Why I mentioned that only ONE of the power connectors should be used on
those SATA drives. BOTH are usable but use only ONE. Besides, there is
no value in using both power connectors at the same time. I suppose
some noobs would see an unused connector and just must fill it.
