I don't have any experience with RAID10, but I've read good things about it.

In my primitive tests, XFS showed good performance for really large files -- 
like raw video files in the gigabytes (as it was designed to do), but small 
and "normal" file size performance is what I needed more and it wasn't 
ideal.  Earlier this year, I used XFS for several months on two servers and 
I liked it.  However, through a bizarre series of power problems, I found 
parts of files wiped out with filler characters.  That made me really 
nervous so I dropped it.

I've had good stability with EXT3 in the past, but its performance wasn't 
something to cheer about.  Despite the problems I had with Red Hat Linux 
support for ReiserFS a few years ago, I use it in most cases now.  It has 
been stable for a while and does a great job for what I need; and of course 
I'm not using a Red Hat OS anymore.  If you're happy with the performance, 
there's no need to change, but it wouldn't hurt to try some tests of your 
own while you're building a new server.
