[DM-MUG] Question on Backup Scheme

[Alan Maupin]

My external hard drive enclosure has two bays with two 1.5 TB drives  
and it provides two options: JBOD or RAID 0.  I've read that OS X  
software mirroring is not a good option since the files must be  
written twice.  I'm operating on Firewire 400 editing DV in Final Cut.
