XFS is the best for long concurrent writes...so if you are not too 
concerned about losing data in a crash (or get battery power backup for 
your 3ware cards and the more cache for your card you have the better) 
but do you also expect a lot of reading while during your writes? Then 
jfs might be better.

You can also use the framework at 
http://untroubled.org/benchmarking/2004-04/fsbench.tar.gz and customize 
it for your own testing.
