Going on a road trip tomorrow. Just want to know if I'll get better battery life watching movies on my MBP if I spin the DVD in the optical drive or if I put the movies on the HD? Anyone bother to do a comparison?
I would imagine that you would get better battery life watching it from the HD but I have no numbers to back that up . If you take a listen to the optical drives in those things it really sounds like it is using a lot of power to run. Also your hard drive will probably still be being accessed at least a little even if you arent playing the video straight from it. Just my 2cents
hd is better. ive done this for about 4 yrs with laptops, always rip them when availible. may take 20 min on AC, but overall, its quieter while watching. and battery life differences are probably about 20-30min
