That's odd. It must be something they've done recently. My 250GB SATA drive is about 8 months old now, and it merely shipped with a short cable with a molex connector on one end and the SATA power connector on the other. So it's basically just an adapter. However, my manual even advised me not to use the molex power connector on the drive. I always wondered why they put it there if they didn't want people to use it.

In the future, does anyone know if we'll be able to daisy chain these SATA power connectors?
