Hi Sparky,
no, unfortunately the SD5 (like the Midjay Plus) has no audio drums, but only an audio track with short loops of percussive instruments (congas, shakers, tambourines, claves, etc), coupled with midi drums on a second drum track.
It's a real pity that Ketron, a pioneer in this kind of technology applied to arranger keyboards, is losing the advantage accumulated in years (see what Yamaha has done with the PSR-950 and Roland is doing with the BK-9).
I am willing to bet that within two years Roland will come out with an Audya 4-like module priced around 1500 euros.
