I would agree with others who state that for a simple key based lookup
nothing beats a dictionary.

But knowing that you are one of the authors of the excellent pytables
module I think you are approaching this problem from the perspective
of reading in a large number of values on each access. In those cases
specialized libraries (like the hdf) can directly load into memory
huge amounts of continuous data at speeds that substantially
outperform all other approaches.
