for large amounts of data, you should ensure that your application opens the open using O_DIRECT.
i have no experience with 3ware controllers, but i have no problem sustaining 400MB/s (4gbit/s) to a Fibre Channel-attached JBOD with an in-house userspace-based application which maintains its own userspace-based filesystem on raw partitions (/dev/sd[b-w]). using 15K RPM disks i can sustain 400MB/s using just 6 disk spindles and what amounts to predominantly sequential writes.
cheers,
lincoln.
