I have data lists composed of many lists (say ~100k) where each list
is ~20-30 items (always the same number); numbers, short strings, True/
False or Indeterminate.

Saving this to disk (using Put) takes ~10minutes, reading it from disk
(using Get) takes ~10seconds.

Does anyone know why such a difference between reading and writing
speeds exist?  A factor of two would seem reasonable, not a factor of
60.
