SATA Pin-Out
The Serial ATA [SATA] bus is defined over two separate connectors, one connector
for the data lines and one for the power lines. A SATA hard drive may also have a
third connector for legacy PATA power connections. The PATA power connector may
be used in instead of the SATA power to supply a connection which is more rugged
and reliable then the SATA-1 power connection.
