Hello all and thank you in advance,

I'm working with large 30min quicktimes of HD footage. They are usually about 150gb+. Usually I"m working with them from an external 1TB G-raid in final cut and they are always dropping frame or freezing! Even when they are on my Mac Pros hard drive (2x2.8 ghz quad/2gb ram) they drop and freeze.

So my question is: what do I need to do to this system so I can view these clips and work with them. I'm thinking Ram. Is it Ram people?
