You should partition your drives anyway: a small, like 1G, partition for
/boot. For swap, the old Received Wisdom was 2-2.5 times RAM; these days,
it's "make swap to be 2G (for emergencies). Put swap on the SSD, I
*guess*... if it's enterprise grade, and not "consumer grade", which will
eventually give up with too many writes.
