Even with parallel processing, assuming you can handle 1G of data per node per second (which is a fairly optimistic estimation for on disk data): 1G/node/sec *

Even with parallel processing, assuming you can handle 1G of data per node per second (which is a fairly optimistic estimation for on disk data): 1G/node/sec * 100 nodes * 2 sec = 200G. 17TB is 85 times that number.
