FreeBSD Preferred RAID controllers

[Gabe]

Hello,

I have to build a file server that will need to run a RAID 0+1 config and I'm looking for the best RAID controllers that run under Freebsd. My entire goal with using RAID 0+1 is having redundancy while utilizing most of the disk space. I realize the potential problems with this setup, the failure of the OS disk and booting for one and also dealing with the possibility of two drives failing within the same set. I guess I can deal with that(?)

Anyway, What controllers have you found work well for you on F*BSD?
