It is my understanding that encoding in Handbrake is not RAM-intensive, but it is CPU-intensive. Presumably, therefore, it is pulling and dumping data off the hard drive as it goes with little buffering in RAM. If that's the correct understanding, and on the given that I am going to upgrade my iMac now that the refresh has arrived, is it worth going to the SSD option? The theory being that access times will be much faster from the SSD than the HDD, so that will further speed up encode times. I would appreciate some comments from those who understand what hardware is used the most intensively by Handbrake. TIA.
