I'm looking at backup options for my MBP, and I was thinking it would be good to have a copy of my drive (made by CCC) as well as a Time Machine backup. For this I'd need two hard drives, 500GB each. If I got a pre-configured RAID system such as the G-RAID mini, would it be possible to use its two drives separately? Would it make sense? If it is possible, how would I go about doing it? I could partition the RAID 0 configuration into two drives, but that doesn't seem clean or correct.
