i'm honestly not sure. i've never bothered to check. i'd guess ~250,000 since although have a lot of DJ sets and extended tracks (classical, concerts, etc) i also have all the DDR soundtracks and what-nto which have ~40-70 tracks of 1:30 a piece.

if this is too much for the DB i'm open to alternate solutions. i just like the professionalism and support currently existing in the empeg/Rio-car line. i only have a 10gb empeg mk1 myself (this iwas #232 or so)... but my friends have 18-60gb Rio-cars.
