I think the original version was 'never underestimate the bandwidth of a station 
wagon filled with tapes driving down the freeway' :-)

tape may have a higher density, but once you include the fact that tape is more 
fragile when transported, and the time it takes to read/write the data on each 
end, the value of RAID arrays of spinning rust compared to tape is very 
attractive.
