Yes, the RAIDing is completely transparent to the OS. You don't even have to reboot the machine if the disks are hot-swappable. Just pull the dead one out, install the new one, and the controller will bring it up to speed. RAID-1 is much faster to rebuild than RAID-5 (just a casual observation; I'm not sure if that's a hard-and-fast rule). > I checked that the card I intended to use (Promise FastTrak TX2) is > supported by FreeBSD so I don't assume any problems installing FreeBSD > either. > > Thanks for any answers :-) you're welcome.
