I'm looking for a 1TB external back up solution. One possibility that I'm considering is the OWC Mercury Elite-AL 1TB RAID 0. Now I don't really want RAID 0, I'm only looking to back up my internal drives so the increased speed I would get from RAID 0 is not an issue, but the less secure nature of RAID 0 is. What I'd like to do is configure the drives as a single contiguous drive (I think this is called JBOD). OWC told me they have firmware that breaks the RAID stripe on the Mercury Elite so that it will be seen as two seperate drives. Once this is done will OSX or someother software allow me to configure the drives as JBOD. I'm not set on the Mercury Elite so if you have other suggestions please let me know. My only requirement is external, 1 TB. I've been looking at FW800 and possibly eSATA interfaces but as this will only be used for back up I'm wondering if even the FW800 is overkill.
