Raidframe works very well. I followed the instructions at http://www.eclectica.ca/howto/openbsd-software-raid-howto.php and my RAID 1 is rebuilding right now. Everything seems to be working very well. I just posted another thread regarding the lack of automatic boot in latest firmware issue. Bryan

Thanks for the feedback. Once the N2100 arrives (which should be tomorrow), I will try it. Bryan

I am really only interested in mirroring so I guess I should just probably use raidframe and see how it goes. Bryan

The link you sent above shows that a particular Corsair module is compatible so I just ordered that module. We'll see when it arrives later this week. Bryan
