I'm thinking about buying the 15" Powerbook released today, and my main consideration is 100 GB 7200-rpm HD vs. 120 GB 5400-rpm HD. Will the 7200-rpm hard drive use more power than…

I posted a thread awhile back all about the 100GB 7200rpm drive, comparing it to the 5400rpm drive, and providing links to pages online that compare them. The brief version is tha…

7200RPM drives have a higher idle power consumption, but the active power consumption is only a tiny bit higher. In both cases, it's not going to make a huge difference in real use…

iomatic: I hear newegg is a good place to buy RAM. Without a specific link, I can't tell if the RAM you're looking at is the same as the RAM in the Powerbook. So the speed is sli…

tooki > can you elaborate on this a bit? Does this mean the 7200 would eat up more battery when the HD is not doing anything? That sounds really bad! When you say the differen…

The difference in power draw is tiny. Below are the power numbers for Hitachi drives, but they should be similar for other brands Hitachi 5K100 (5400RPM): Startup (peak, max.) 5.…

Wow, that's an extremely helpful post, Mark. I hope your numbers are right. But I've read your posts before and found them informative. I'm still nervous about pulling the trigger.
