I use 7200RPM disk, Hitachi I bought at SLS. I installed it first day I got MacBook Pro unibody, so I don't have exact figures to compare with 5400RMP drive.

But, I'd say, the new drive shaves off some 30-60 minutes of battery usage. Never been able to get more then 4hrs with 7200RPM drive. And the difference in speed compared to 5400RMP drive is not much...

I guess SSD is really the way to go.
