That really depends on the software you use.  Just fetching mail on my
machine causes about 500 MB of data written to disk.  That's because
I'm using Gnus with nnml and slightly large mail folders and Gnus
rewrites those index files from scratch each time new mail for a
folder arrives.  I should really consider this a bug and fix it, but I
haven't yet found a good solution.
