I have done it in the past with with mediocre success... drive failure brought 
down the box - but once I disconnected the drive everything worked off the 
mirror. Other than that, it seemed to do its job. But then again, on the web 
you hear from all the people with issues with linux software raid - sata or 
not.. 

If you have the money and its something important, buy a hw raid controller - 
3ware 8006-2 controllers are fairly cheap (around $130) and so far I haven't 
had any issues with any of the ones I use. They are really worth their 
money... and no, I don't work for them :-)
