I disagree. On most raid-controllers we use XFS has a significant advantage over Ext3 when it comes to large sequential writes. Ext3 gets nowhere near the bare metal performance.
So, in short, I think it will be interesting to see how Ext4 performs for this.
Exactly. There are differences between file systems even when using very large files sequentially. I did benchmarks on various controllers and my experience was the same: the file system does matter.
