Just for fun, I tried updating the firmware so that our existing SCSI
card would support mirroring. That did not work, so hardware RAID
is off the table for now.
In this case, given the limitations of the card, hardware RAID would
have been less desirable anyway, perhaps, because the card only
supports 0 and 1, not 5. This would limit us to 36GB of disk space.
With software RAID, we can do RAID 5, so that our 3x36 can work as
72GB.
So, I think that's what we should do.
