connector?

No. They use a new style small connector adjacent to the S-ATA Data
connector. However, current S-ATA drives are often coming with the old-style
molex for compatibility reasons. There are also adapters available for older
power supplies. The new ATX spec coming out will have the new S-ATA power
connector, so new power supplies should start showing up with it.

I see, So when I get a drive, I got to make sure what connector it got.
Maybe they should have stuck with the old power conectors, they seem to
work ok.

On the data cable, yes. The signalling is 250mv instead of the 5V signalling
that P-ATA uses. But, the S-ATA *power* connectors still supply 12V (motors)
and 5V (logic) just like the old molex connector, but the S-ATA power supply
connectors now also supply a 3.3V source for anticipated future low power
mobile devices. In today's desktop machines, the 3.3V is not utilized on the
S-ATA drives, so a simple adapter for the standard 12V/5V AT/ATX molex
connector is available to fit the drive. Many drives are also still coming
with the old-style molex anyway.

Now we know, thank you, I did not think the motors would have a lower
voltage.
