You'll have all sorts of troubles with Ext3 once you step deeper into 
the TB zone.

Just use XFS. That's what we did, works fine for us. And it's typically 
faster when the files are very large (especially delete is very fast).

No other filesystem will be as reliable as Ext3 if the machine suddenly 
loses power, but if you have a battery backup or something like that, 
you should be fine with non-Ext3 filesystems.
