FreeBSD has always automagically recognized my RAID0 array (Promise onboard 20265 and 20276). If you set up the RAID array before installing 5.1 you should be fine. There are also FreeBSD HD management utilities that can be used to create and manage RAID arrays (e.g., atacontrol), but I haven't used them. > - If one of the 2 hard drives fail, the data will still be visible and > accessible on the remaining drive correct?

You are describing RAID1, not RAID0. Some reading about RAID before you do this is recommended, I think. :) Jud
