The big big advantage of using geom mirror instead of a "hardware RAID controller" is: The disks will boot and run in _any_ system that is capable of using the disks at all. Dedicated RAID controllers lock you to the specific brand and sometimes even model you use. Bad for desaster recovery. With a geom mirrored SCSI or SATA disk, if an entire system/mainboard/CPU fails, I simply plug the disks in the next spare box available, boot, possibly change name of network interface, done. With hardware evolving so rapidly nowadays you cannot guarantee to have another identical controller on the shelf when you need it. Happened to us with ICP-Vortex (iir) controllers. ROHS - product unavailable :-/ Successor not compatible in terms of on-disk data structure. We are now happily running RAID 1 and RAID 1+0 with geom.
