Hey Jerry
thanks for the info.
No wonder I remember having dropped frames in playback when editing in a frustratingly small space set-up with a 20″ white imac sometime last year.
I was wary of getting an imac but based on the new specs it seemed like they’re value for money for what I want to do – light editing at home.
So my new imac is just a couple weeks old and its internal hard drive space is 320GB… I don’t need more space yet. I’m not in USA and I haven’t heard those brands of ext drive brands you mentioned but I get your drift; will try out drive compatibility next time when I have one.
Just really happy to be able to run FCP at home!
