It seems that mercurial is optimised for mechanical discs, but a mutually
exclusive optimisation is needed for SDDs (space is expensive but random
access is cheap). Could this be an option to configure when the repository
is created, similar to the way that MySQL lets you choose a storage engine
when creating a database? (Obviously not quite the same, because the UI
would be identical either way - it's only the internal storage algorithms
that have changed.)
