This may seem like a stupid question, and please take no offense, but why copy the data, when it can be played fine right from your NAS?
I do this and never seem to have any issues. Of course having the media right in your core, may yield some performance gains, but if you have a working NAS on the LMCE network, you should just be able to use it. And then perhaps save your 2nd drive for storing more media, in addition to what your collection already has.
Just a thought.
