There are lots of times when you would do a large content aware fill. One example is when you stitch five images together to form a panorama. It leaves a ragged edge all the way around and you have to do a huge crop to get it to a rectangle - OR - you can fill the ragged edges using content-aware fill. Another is when you have pushed important things too close to the edge of the frame to be able to crop to 8x10. You can use content aware fill to artificially create the missing image on one end.

I also have an i7 but only clocked at 2.8GHz. With 4GB RAM it basically locked up when I tried to do a huge Fill. When I increased it to 12GB RAM it reduced it to just a second or so. It must be using RAM for something.

I don't have any SSD's. I have two 2T eSATA internal drives.
