Maybe you should tell us a little more about your actual application before we get too distracted by "I can't do X because Y" without having any justification for the assertion? Interesting additional information may be:

  1. How many read accesses per (whatever appropriate period of time)?
  2. Will the same 'word' be accessed multiple times per period?
  3. Is the same root comprising the first n characters likely to be accessed multiple times per period
  4. What is an appropriate period?
  5. What are the constraints on the time it takes to build the 'database'?
  6. What is 'very fast'?
  7. Is there any point compressing the values?
  8. What else might influence a smart solution?
True laziness is hard work
