Uh... Ok, this might be an option generally but honestly not for me ;)

Considering the money I've spent 3 years ago for buying the RAID
controller and considering the load it takes from the system handling
the RAID I think it is in the best interest for the system to keep the
RAID-5 3ware internally. As you might have seen the system is not the
fastest one with not that much of memory - so whatever load I can
delegate I'm try to delegate off the CPUs.
Today I would probably not spend the money buying a RAID controller again
but use indeed ZFS instead. But back the time there was only (g)vinum -
and I never liked it.
