Personal experience about FFS reliability: never more than just minor damage
even on heavily loaded machines. The same applies to Linux' ext2fs though
it is in theory a bit more vulnerable to corruption as long as not mounted
with -o sync. The performance specially for handling lots of small files
is everything else but not comparable. I found ext2fs MUCH faster due to it's
asynchronous updates of the fs meta information for that case.
This has nothing to do with the filesystem. NetBSD (and I believe
FreeBSD) supports a flag that will let you mount the filesystem
asynchronously (wrt metadata writes). However, it is not the default,
and most unix-seasoned people consider it just asking for trouble.
