I appreciate both of your comments. There are alot of possibilities for hard drive setups.
As I said before, hard drives are the bottle necks of computer hardware. One needs to
buy the fastest with the most throughput possible. Video editing is very taxing on hardware. Video work involves waiting for the computer to catch up to you quite often.
In pro editing rooms, you will see huge raid setups and super fast computers because you
can do more in real time. When you have hours of footage, the faster you can go, the more customers you can serve. I myself am not a "pro editer", but I am a modding junkie with a need, a need for speed.

The more informed you are, the better choices you can make.
