Questions with respect to "the best" are always very difficult...

There are the UML-diagrams for the ZODB, a tutorial and
Tim's details about "FileStorage".
Please, do not ask me where to find them. I forgot (and will not search
for you).
I have not seen a documentation explaining why it is as it is.

Implementing a storage should not be difficult (and does
not require deep ZODB knowledge).
It essentially is a map of oids (8 byte strings, locally unique)
to opaque data. Derive from "BaseStorage" and override
methods as necessary.

That's a bit more complex.
I might help should you have concrete questions.
