Its a neccessary part of RAID because duplicating raid functionality in every

Seen the RAID-Z system in Solaris 10?

Or the Write Anywhere Filesystem used by Netfilter?

It's clear that you can get better performance and reliability by
codesigning a filesystem with the block layer. I think of the
difference between old-school Unix (KISS) and System 370: do you build
a system that's simple and clean, or do you take the extra effort to
maximize performance. Sun can afford to do this because it isn't
wasting energy on maintaining 30 filesystems that almost work, but
rather focusing on one that does.
