This morning my MBP arrived and I installed the WDC scorpio black. It's running great, however, apart of me is starting to wonder if 320 gigs is going to be enough. I'm going to put all of my music and recordings on a 1TB firewire external, which will leave around 277 gigs on my internal WD drive for temporary files, etc. Do you guys think I'll be okay with keeping the scorpio black inside the MBP? (I got the WD because it had better ratings and was reported to have that click/beep issue as the seagates). Anyway, rant aside, I am completely enamored with the computer. It's blazingly fast and so snappy. I could not be happier.
