late 2008 Unibody MacBook: effect of HD upgrade on battery?

[mrmarbach]

I have a 2.4GHz late 2008 Unibody MacBook.

Thinking of a HDD upgrade. I believe 750Gb (9mm) is the biggest I can go.

The question is: will this affect battery time? I'm guessing not as these drives are 5400rpm as well.

(1Tb 12mm won't fit, will it?)

TIA

I even put a 7200 RPM drive in mine (same model) with no ill effect on the battery, so you should be good there. You can use a 1TB 12.5mm drive if you like, although I would recommend the samsung 1TB that is 9.5mm, as they are a good bit faster.

Have you actually tried that? Has anyone else? Would be a great solution for me, as I have a 1Tb external dangling off it all the time...

I put a WD Black 7200rpm 320gb a 2 years ago and it definitely is faster and the battery life isnt big enough of a difference to notice. The macbook unibody is unfortunately weak battery life compare to the new mbp...
