I don't think this is right. The RAID-1 volume I'm using right now is with two drives attached to a non-RAID card with a Promise chipset. I also get the impression -- though can't test it right now -- that the atacrontrol-based RAID will work across cards.

It would be, but the RAID on the Promise and Highpoint devices is not true hardware RAID. It's just software RAID with the drivers moved over to an EPROM on the card. I know from my own experience and that of other people that the Linux software RAID outperforms the "hardware" RAID of these devices. I'm willing to bet that the FreeBSD RAID at least comes close, if not betters the Linux performance.
