If I'm not mistaken a 7200rpm will decrease battery life and run warmer than a 5400rpm drive.
 
The 320/5400 drives have greater data density/platter, thus the dramatic improvement in performance. Your 120 wasn't near the current density of 320 drives.

everybody's only talking about the 320 GB drive. So again my question: Is it the same for the 250GB/5400 bto-drive? I'm asking that because I only wanna choose between the drives that are offered with the mbp.

Can somebody clarify that for me?

does anyone know the exact name of the 250GB 5400rpm and 200GB 7200 GB so I can compare them myself?

Have a look at the Tom's site report on notebook drive performance. There are only a few 250/5400 drives currently on the market, and they all pretty much bunch together (except the Samsung, which is appreciably higher). I don't know which 250 gig drive Apple is putting in their laptops, so it's impossible to give you a precise answer. If you can find out what drives Apple is putting in for their 250/5400 and 200/7200, it would be much more informative.

just to make sure: the best one's always on top, no matter what category? :eek:

While it will generate more heat, it will have no impact on battery life.

A 7200rpm drive (assuming 160GB+) draws more current at idle than the Fujitsu HDs often found in recent base model MBPs. Therefore, upgrading from a 160GB-200GB 5400rpm drive to a 160-200GB 7200rpm drive will reduce battery life somewhat. However, the energy consumption of a 200GB 7200rpm drive may actually be less than that of a 320GB 5400rpm drive (especially the power hungry WD Scorpio 320GB).
