1. A system comprising:
a first data node comprising:
a first storage medium having a first performance criterion;
a second storage medium having a second performance criterion that is substantially different from the first performance criterion; and
a second data node comprising a third storage medium having a third performance criterion;
wherein the system is configured to:
store a first copy of a piece of data in the first storage medium;
store a second copy of the piece of data in the third storage medium; and
schedule a computing job associated with the piece of data to the first data node based, at least in part, on the first performance criterion, second performance criterion, or third performance criterion, wherein the first performance criterion, second performance criterion, and third performance criterion are based on at least one of a speed, latency or throughput.
