I will be downloading roughly 650 GB of music files to a 1 TB external HD. When I play back the music which HD will be best for my needs a HD with 64mb cache 5400 rpm or 32mb 7200 rpm?

Seriously? Unless you're going to be playing back 1000 files all at the same time, it really doesn't matter what you get. Playing mp3 files is not an IO-intensive task.

Either HD could handle playing your music back without a problem. Cache is useful... sometimes. But faster spindles are always better to have, performance wise. Go for the 7200.
