Hello everyone, I'm considering picking up one of the new MacBook Pros, and I'd really like to get the largest drive available on the 15", the 200GB drive, but I do video editing and am a bit wary that the 4200 rpm nature of the drive just wouldn't do it. Can anyone advise as to what would actually happen if I were to edit off of a lower speed drive? Would I just get a lot of dropped frames? I would be editing mainly DV content, although I would likely be editing some HDV content off an external drive (I just don't want to have to tote that around with me at all times) Also, would a 4200 rpm drive be capable of smooth HD playback at, say, 1080i? Thanks for your input!
