The only metadata that matter are the inodes and (for ffs) the
indirect blocks.  You do really want the latter to be single disk
blocks - many systems actually write them synchonously.

The inode is (probably) only 128 bytes, losing an inode block
will lose the other files.

A journaling filesystem probably already has ways around this...
