Allmost all of the software playback programs for the MAC have the option to preload the track to main memory for playback.  This option preloads the songs to core memory before it plays, essentially playing from memory (SSD type storage) vs reading from the hard drive while playing.  I have found that this option yields the best results.

My question is whether or not an SSD drive would yield any sonic benefits if you are using the preload to memory option.

Thanks for any input.
