    I like having the "put the hard drives to sleep when possible" on, since I have 4 internal drives and they do create some resonance/noise. And often I just use one or two of the drives. But I guess it's not really that healthy on your drives to spin them up and down often, so I wonder if there is some way to change the time the drive has to be idle before OS X spins the drive down? I guess it's at 5-10 minutes by default, I might want to set it to 30 minutes instead. Possible?

    Yup, you can do it from the terminal.

    pmset -g will tell you the current sleep wait in minutes, on the disksleep line.

    sudo pmset -a disksleep 42 would set the wait to 42 minutes, and so on.
