cd/dvd drive vs. hard drive power consumption

edited July 2007 in Technology
I have a question about power consumption on a laptop, which would consume more power an average cd/dvd drive or a 5400 rpm notebook hard drive? My reason for asking is I want to watch some TV shows on my laptop and want to know if I should burn them to DVD to lengthen battery life.


  • I'm pretty sure hard drive is the way to go. Your hard drive is going to be spinning constantly anyway (even setting it to turn off wouldn't help much.) and it reads much faster so its not constantly consuming power; reads a bit to RAM then stops, also, much more convenient.
  • Thought so, thanks.
