I happily purchased a Canon HV20 recently, and have been researching external hard drives for my footage and as a scratch. From what I've been told and read, it would be best to use a firewire HD, but the problem is that I'm on a Macbook Pro with only one firewire port, and it's hooked to the HV20 for import. Would it be a good solution to just import to the MBP HD and then transfer the files to the external when completed? Or should I look into some other set up? How do you deal with storage and Import?
