Nope.

Yes, there you have a goof point. If you have large volumes of writing,
a postgres backend my (at least in theory) be faster.

Then you have backups. ;) Data is never written to the middle of 
Data.fs, so this would be a very unusual problem.

Well, neither does FileStorage. The index of objects is in a separate 
file for example.

It enables you to use multiple processors and multiple computers more 
efficiently, so it's always a good idea for big sites, no matter what 
storage you use.

Absolutely.
