Ellen,
I use several external hard drives for my video projects.
When looking for an external hard drive, look for a drive with the following:
- 7200 RPM spin rate
- 8 meg cache
- power switch on drive case
- USB 2.0, Firewire
I use the Western Digital drives and have had no problems.
I connect via firewire, and can stack up to 56 drives from just one firewire port.
If you plan to connect via USB, be sure you have a USB 2.0 port on your computer - if you don't have USB 2.0, the access speed will be quite slow.
