The problem with option #1 (making it into a drive) is that 
the input/output data is too large for current SSDs (i.e., 
terabytes in size).  And while the programs are all open 
source and we could modify them, currently, they don't make 
use of external disk (SSD) space.  And I'm not sure if doing 
is straight-forward.

I have to admit that this was an awesome analogy!  Put a 
smile on my face while I was at work...  :-)

I see.  Thank you for these other options!
