Should I be aware of anything before installing this a macbook pro?

Yeah - it doesn't make the spinny sound you're used to hearing when you hit the power button. Verrrry disconcerting the first time 😱; the sound of heaven thereafter 😀.

I had a first gen 80gb in a MBP. It was quite heavenly, save for the small size (I eventually went for the 500gb 7200rpm).
