Hmm.  Seagate's current 9GB 7200 RPM drive, the ST39236LC draws 7W when
idle.  Their current 9 GB 10k RPM drive, the ST39204LC draws 8.5W when
idle.  IMHO, that's not really very significant anymore, especially when
your CPU eats 20-70W.  Both of these numbers are way better then drives
only a generation or two back -- last year's ST39175 (9 GB, 7200 RPM) drew
9.75W when idle.
