OK, I am sorry if this seem silly and I'm completely missing something.

But I am confused as to the above specs.

Is your Master and Chunkserver on the same machine?

or are those 32 x 2TB drives spread out on how many chunkservers?

Our experience has been the more chunkservers we have, the better the 
performance because the read/writes are spread out among the 
chunkservers  (in addition to individual spindles on each chunkserver).
