  6. Some HDDs won't spin up unless the SATA data cable is connected to a host controller. Such HDDs would save on power.

    Alternatively, some WD HDDs support Power Up In Standby (PUIS) via a jumper, so you could install a switch to select one or the other. But that's a little exotic for most people.
  7. Thats pretty cool actually, where can I get those jumpers youre talking about? :)
  8. WD drives have a PM2 jumper. You could run wires from the PM2 jumper pins of two such drives to a DPDT switch. When the switch is closed, the jumper is enabled. When the switch is open, the jumper is disabled. It's not a setup that would be available off the shelf. You'd have to build it yourself.
