Any advantages to using SATA Power lead instead of molex?

Hi,
just got time to build my new system. Had the parts laying here for one
month. Anyway I am using 2 x Raptors which have both Molex and SATA power
plugs. My ANTEC PSU has 2 SATA power leads. I seem to remember that you
can *Hot-Plug* hard-drives if you use the SATa power leads. . is this true?

If not I may as well just use the old style molex. . .
 
The procedure for hot plugging a drive is attach data then power cable, and
detach in opposite order.

There is a chance with molex that 5/12V connects before GND, but since the
data cable also has GND this may not be an issue.

SATA power and data connectors always connect GND first.

You're more likely to run out of those tho.

It's sorta true. Read the manual for your board--regardless of what the
standard says some of the chipsets that are out don't support hot-plugging,
and then there's the issue of support at the system level. If the
operating system can't deal with the drive being hot plugged then there's
not much point to it even if the hardware allows it.
