I am looking into getting some home recording equipment. Currently, I am using a MacBook Pro laptop with an Intel Core 2 Duo processor (speed is 2.53 GHz) and a 4 GB memory. I am leaning towards buying Pro Tools, but I am concerned about filling up my computer's memory and slowing it down. If I were to buy a 2 terabyte external hard drive, would it be possible for me to hook it up to my computer and send all the files there so as not to negatively effect the computer's speed and usability? Or am I going to have to possibly purchase an entirely different computer to use solely for recording? As you can tell, I'm completely new at this, any and all help is greatly appreciated!
