It has 120 drum sounds. They're pretty darn good too

I've listened to the Demos for the PSR-3000 at Yammies site, and I have to say that the Boss DR-3 has the PSR-3000 beat in the drum department. The acoustic kits on the DR-3 just seem so real, and with the effects they're even better. (not knocking the PSR-3000 either--personally I'd love to have that keyboard). It's just that I was disappointed to see Yammie carry over the dated kits once again to the PSR-3000.
