I've made changes in the mount options, along with tuning journaling for ext4 filesystems, and so far have yet to encounter corruption (lots of small and big files):
* data=writeback * nobarrier * nobh * noatime * noauto_da_alloc http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/filesystems/ext4.txt;h=7be02ac5fa36d7f4c07856fe9cf89391e08986f7;hb=HEAD Optimally though, it's not recommended if you'll use ext4 for lots of small files (better use an embedded like sqlite for storing such). Using the default mount options though I've encountered massive file corruption (and jettisoned usage of ext4 for quite some time).
