eSATA goes power-cable-less

The Serial ATA international organization is working toward a new specification that will do away with a separate cable for power and instead deliver power over the eSATA cable. This ought to reduce the advantage that some USB and FireWire disks have on convenience. SATA 3.0 (3000 Mbps) still does better on speed than USB 2.0 and FireWire 800, though USB 3.0 (4800 Mbps) and FireWire 3200 (3144 Mbps) would catch up soon.

Note: USB 2.0 works at 480 Mbps and FireWire 800 works at 786 Mbps.
