if you are really worried about silent filesystem corruption caused by
bad hardware, I strongly recommend investigating Solaris' ZFS, which
can detect and repair data corruption assuming you have some
redundancy (ie. mirror or raidz). plus it's always consistent on disk
(no fsck, ever). and you get ACLs, snapshots, online expansion, ...
the list goes on.

and getting back on topic, ZFS works very well for Maildir :)
