I'd tend to recommend ReiserFS or XFS first (to me Reiser is better, XFS
second...Reiser seems to handle corruption a little better, except in the
case of tail  corruption in which case you lose all the tails on the
filesystem possibly), followed by ext3.  Ext2 isn't an option because for
500+G you need journalling.

I should also note that I say reiser's tools are better because they actually fix the filesystem. XFS we've had filesystems never quite fix after needing to be fixed by the xfs tools. They kept coming up with more errors, or crashing the machine despite the filesystem checking out as 'fine' after forcing a full check.


Reiser will take a while to mount such a large filesystem....As may XFS.
I haven't treied anything that big recently with ext3 but you can try
it...though I'm kind of interested now so I might see myself.  My
benchmarks would be out of whack with yours though because of CPU and
storage backend differences. :)
