If your just doing RAID 0 or 1, you can get away with using and  
geom_stripe and gmirror.
Both are very mature and I would be comfortable running either in  
production.

RAID 5 is another beast, and your better off going with a hardware  
based solution if it fits in your budget.
Its going to be much faster, and more reliable.

My rule of thumb is if your budget allows, always go with the  
hardware based solution ;)
