Internal or External Hard Drives for Events and Projects

I'm waiting (yum) for my new 2012 iMac to be delivered. 27" i7 chip, 32GB RAM, fusion+3TB internal hard drive.

Is storing my Events and Projects on an external hard drive (I'll have Thunderbolt on the new iMac) a better technique vs. storing on the internal hard drive?

I currently have several 2TB external G-Technology hard drives that use FireWire 800.
I'm considering a G-Technology 8TB Thunderbolt external hard drive, but am researching reviews for the Promise Pegasus RAID Storage with Thunderbolt (anyone use this product?)

My videos are relatively short (generally 10-15 minutes).
Is doing all my editing on the external hard drive better than keeping everything on my internal hard drive?
I have been keeping my Events/Projects folders on my internal hard drive and have not noticed any particular problems.
However, I have read numerous articles that say to keep my Events/Projects and do all my editing on an external hard drive as the internal hard drive is busy doing a lot of other stuff.

Thanks for any advice.

Always.

The internal hard drive is where the software and OS dwell. Video editing is one of the most taxing tasks a computer can attempt. Whenever you have a choice, it's always better to use another drive.

Thanks. That's the conclusion I was reaching. Am looking forward to a Thunderbolt external hard drive.
