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. See http://untroubled.org/benchmarking/2004-04/2.6.5-gentoo/ You can also use the framework at http://untroubled.org/benchmarking/2004-04/fsbench.tar.gz and customize it for your own testing.
